Welcome to another informa ve edi on of Africa's favourite Bi Monthly magazine; bringing you all the latest news about construc on equipment, industrial machinery, mining projects, technologies, investment opportuni es you'll want to get your hands on in 2023.
Africa Mining Insight is a marketplace, a communica on hub and news source for advancing mining Industry businesses in the region. Abundant resources, an advanced mining sector, robust financial systems, a progressive legal framework are the gateway to African markets.
A robust mining sector is broadly understood as a fundamental path to economic growth and development. The key boon of mining is that it absorbs large swaths of workers and places them into produc ve and decent paying jobs. Throughout history, this exact recipe has transformed the United States, United Kingdom, France, Japan, and Germany into some of the world's wealthiest na ons.
However, this narra ve seems to exclude many African na ons. Despite their manufacturing poten al and promising trajectories, most African countries have remained rela vely dearth of factories. This limited industrial development represents a missed opportunity for economic transforma on and quality employment genera on that alleviates poverty
Today, leaders are increasingly realizing that the mining industry is a major factor in helping Africa achieve its goals and successfully reaching the next stage of economic development.
In this edi on we will look at Mines and Money Connect London which th will take place on the 25-26 April 2023, being Europe's premier mining investment event, connec ng miners with money and investors with opportunity. This issue will also include geosynthe c solu ons from Naue, Carima's produc on and formula on of water-based lubricants, for the installa on of op cal fibers and electrical cables. Çlean-in-Place Electrowinning from Cadia systems, Redeployable Turnkey Explora on Camps, air scrap dust control and heavy minerals mining are some of the top headlines.
Thank you to all our authors, subscribers and adver sers for helping to shape not only this edi on, but also the very fabric of the magazine.
Best regards Goodwill Sibanda

Çlean-in-Place Electrowinning. It's a concept that when you see it in ac on seems obvious. But for years the process used in ADR plant goldrooms in gold mines around the world, has involved the removal of individual cathodes from the electrowinning cell by means of overhead gantry to a dedicated wash-bay for recovery of gold sludges.
“It's me consuming, ergonomically demanding on operators and fraught with the poten al for gold sludges loses to the goldroom floor” says Sean Galvin, Engineering Manager at Cadia Systems – a Perth based mining equipment manufacturer
Mr. Galvin was, for over a decade, formerly manager and designer at the Equipment Division of Como Engineers – another Perth based Engineering Consultancy and Equipment manufacturer. Having been responsible for design and commissioning of goldroom equipment and modular elu on systems worldwide, he first hand experienced the short comings of cell cleaning - even on the electrowinning cell designs he had been responsible for
Issues common in goldroom cell cleaning ac vi es include dealing with heavy lids requiring either counter balances for winches to li open, slow movement of overhead gantry cranes when reloca ng cathodes or anodes, heavy cathodes which were o en man handled in and out during cleaning processes, and problema c connec ons of
cathodes and anodes to the main busbars.
“I remember commissioning a system for Metso in Finland in 2011 on Christmas day” he states, “they were 800 sized cathodes with 40 cathodes over two split cell designs.”
“A er moving the first few to the wash-bay using the overhead monorail I just gave up”.
Mr Galvin instead proceeded manually hauling the cathodes out of the cell one by one and laying them on top of the remaining anodes and cathodes in the cell. “That was my version of clean-on-top of cell”, he laughs. Cadia Systems specialises in the development of innova ve technologies for the gold processing industry. The business has a strong focus on cleanroom style technologies that bring safety improvements for operators. The equipment also has a clear design focus on improving recoveries and op mising performance.
Their proprietary protected EC Clean-in-Place Electrowinning Cell was developed a year a er Mr Galvin started Cadia Systems.
U lising a novel automated li ing mechanism, the cell li s the anodes and cathodes away from the main connec ng busbar connec ons, allowing the anodes and cathodes to be slid one by one across the cell to provide access to the cathode face for insitu, in-cell washing.
An addi onal clever addi on to the cell designs include a near neutral-pivot, low
weight/high rigidity cell lid. The lid simply slides back with a minimal operator pressure to the front of the lid. For larger cells, which can be as large as 1200mm cathodes in size, the lids are also available with automated opening and closing.
The cells also have front mounted busbars that are located out of the vapour zone to minimise corrosion from ammonia fumes. The busbar contains stud connec ons which provide ght inter-busbar connec on ghtness to avoid hot-spot connec ons. So no more losing those pesky nuts. A guard protects the busbars when in opera on, but also forms part of an inbuilt keyed locking mechanism for security of the precious metals while in opera on. Anodes are manufactured to provide longer design life me, and cathodes can accommodate either mild steel or stainless mesh or more common pre-made pillows.
“The product has really been a great success with clients!” says Mr Galvin, “Goldroom operators love them and site management love the enhanced safety and recovery aspects”
Cadia Systems has also entered a collabora ve arrangement with Gekko Systems for the design and supply of modular elu on systems using Cadia's equipment and design experience and Gekko's world-class engineering, manufacturing and support services.
Fluid Systems Africa has recently been appointed as the official partner of Arpol flexible pipe couplings in Africa. Arpol designs and manufactures flexible joints for the connec on and repair of all types of pipes and industries.
Arpol flexible couplings connect pipes be er, faster, safer and at a lower overall cost than conven onal systems.
Our Scope of Supply
Arpol was founded in 1976 in Barcelona and specialises in design and manufacturing of flexible couplings for all types of pipes and applica ons.
We supply a wide range of couplings for many applica ons. Our size range is 48mm to 3000mm and pressures from PN16 up to 1300mm, and PN10 up to 2000mm
Some of the sectors that put their trust in our flexible couplings are water purifica on and treatment plants, chemical industry, power sta ons, domes c installa ons, civil
construc on and engineering, mining, and bo ling plants. But they are not all, as we con nue to seek out new sectors where we can be of assistance.
In many cases, new pipelines involve pipe materials that are different from the previously installed pipes, and can create diameter differences that even though minimal, can become an inconvenience when old and new lines are to be connected.
Arpol couplings can be used to repair any point of the line, but also to connect dismantling pipes to different hydraulic pieces (valves, pumps, etc.) as well as different material pipes.
Arpol couplings are a great solu on to connect different diameters and make them the most reliable tool for hydraulic sealing. All Arpol couplings allow certain tolerance to solve common old-line problems like angular deflec ons, pipe separa ons, se lement correc ons, rough surfaces etc.
Quality is our guarantee. Our mission is to offer our customers the best possible solu on to the problem they face. To us every project is unique, and we do our best to offer the flexible coupling that best meets the customer's needs. Our products are guaranteed by the constant quality inspec on they undergo in our Barcelona factory
Solu ons are our iden ty.
We a ach great importance to our R&D&I department. Our goal has always been to offer solu ons to the challenges that arise in the market. The world evolves and we evolve with it, so we are in a constant process of innova on.
“Because connec ng ma ers” is not just a slogan, it is a way of working. We take the me to listen to and understand the individual needs of all our customers.
We are present in more than 40 countries, and we aim to be in many more including Africa.

With the use of electrical equipment comes the real risk of arc-flash incidents. Recent advancements in arc-flash mi ga on technology now enable mines around the world to cost-effec vely mi gate arc-flash hazards to protect both personnel and equipment. One pulp and paper customer recently reduced their arc-flash incident energy by more than 90% by using a highspeed arc-flash mi ga on solu on from Schweitzer Engineering Laboratories (SEL) that included feeder protec on relays with op cal sensors.
However, when making capital investments, the sporadic nature of arc-flash events can cloud the issue. When everything is working properly, it's easy to take arc-flash safety for granted. You're not alone if you some mes wonder if arc-flash dangers are overstated when months or even years pass without incident.
This was the case for an electrical engineer at a North American mining opera on who always wondered if the investment he was making in arc-flash technology would pay off One Monday morning, upon returning to inspect the plant's new switchgear installa on, he learned that an arc-flash event had occurred over the weekend. However, as he surveyed the affected
switchgear, he no ced that only a small layer of dust covered the equipment. The power protec on scheme from SEL had operated correctly, and provided event informa on that enabled them to understand what had occurred. Knowing the poten al havoc that an arc-flash event could have caused, the lack of damage surprised the engineer “What was humbling was that the unexpected happened,” said the engineer, “…and [the relays] protected our equipment from poten ally devasta ng damage.”
The primary objec ve of installing arc-flash protec on equipment at the mine had been to ensure worker safety. But, the protec on scheme also protected the mine's newly installed switchgear and prevented an expensive disrup on to the mine's opera ons.
As he reflected on the calamity that had been avoided, the engineer felt fortunate to have incorporated arc-flash mi ga on technology from SEL for many years throughout his facility. Regardless of how rarely arc-flash events occur, given the poten al consequences, it is cri cal to be prepared. For this engineer, protec ng personnel, equipment, and ongoing opera ons proved to be a solid investment. For further details about this customer and his arc-flash
protec on scheme, please read the SEL customer case study at h ps://selinc.com/Solu ons/Success -Stories/Mining-Arc-Flash/ SEL understands that it's cri cal for mines to stay up and running, and we design our solu ons to help ensure reliable and con nuous power for mining opera ons around the world. You don't have to experience an arc-flash event firsthand to understand the severe consequences that can occur.

The use of geosynthe cs in mining opera ons grows annually as mining companies focus on the technical and economic advantages of geosynthe cs. In this regard, Naue can
· support the economic extrac on of valuable resources in heap leaching,
· offer engineering solu ons for mine waste and water management in tailings facili es,
· provide sealing, drainage, filtra on or separa on materials for all kinds of ponds or mine remedia on of old mining opera ons,
· deliver reinforcement and stabilisa on products and systems for embankments, haul and access roads or steep slopes and walls.
This means that our polymeric materials enable more efficient barriers, stronger access roads, space-saving and safety-enhancing retaining structures and much more. But mining projects are o en sensi ve to the environment and are located in remote areas. Therefore, our geosynthe cs can not only offer cost and me savings but also reduce the environmental impact (carbon footprint, energy consump on) on most projects involving geotechnical work compared to conven onal methods.
® Our HDPE geomembranes Naue Carbofol are extremely durable with a great cost-benefit ra o. And in parallel, they are an important line of defence to protect the environment. The applica on of our reinforcement and stabilisa on
®
® products Naue Secugrid and Naue Combigrid results in a reduced need for quality engineered fill material for sub-base reinforcement. Our ® geosynthe c clay liner Naue Bentofix or mul component GCL Bentofix X can replace clay
In both cases, the transport costs to the site will be
reduced, and the speed of construc on will be increased. To sum up, the costs of construc on materials such as aggregates or concrete, construc on me and environmental impact will be reduced significantly
You can use our geosynthe cs individually or combined as an intelligent system solu on. They are built to last for long-term usage when properly designed and installed. Naue can provide
· engineering, specifica on and design support,
· so ware tools (for base courses, slopes and walls or working pla orms),
· tes ng (e.g., shear box tes ng, leachate tes ng),
· training and supervision,
· installa on.
Design and specifica on of the solu on should be carried out as early as possible within the scheme's development and guided by appropriate ground inves ga on.
For example, heap leaching. Without ques on, heap leach has become an enormous driver of the growth of mining opera ons wordwide. 25 years ago, only about 3% of copper and gold supplies were produced through heap leaching. Today, the volume surpasses 30% annually. Valuable chalcopyrite copper, previously not considered economical in heap leach development, is now heap leached, as is nickel laterite, uranium, and even rare earths. Heap leach stacks can be up to 200m, as opera ons look to prove site yield more quickly. Heap leaching accomplishes this – but only with the containment support of geosynthe cs. Geomembranes and geosynthe c clay liners (GCLs) are used in lining system solu ons as heap leach pad liners, pregnant solu on trench liners,
processing pits, onsite water storage, “raincoat” covers over ore stacks to shed stormwater – rather than dilute the leach heap solu on – and onsite wastewater management. Geomembranes are not all that mining sites require. Nonwoven geotex les provide long-term, robust protec on of and fric onal stability for geomembranes on difficult terrain and in tall ore stack scenarios.
The second example is TSF. When an ore's valuable deposit is extracted, what remains of the ore is waste. O en, it is a high percentage of the ore handled at the mine. Poten ally contaminated from the extrac on process or containing environmentally harmful components, tailings must be isolated to prevent long-term environmental damage. As mine sites increase in size, the engineering needed to properly contain the volume of tailings has intensified. This scaling up of containment frequently requires not just lining systems but reinforcement and sealing systems for perimeter berms on tailings pond. Weaker, earthen-only berms are at risk of satura on, erosion and failure.
Furthermore, the increasing depth of tailings storage ponds requires a stronger containment engineering design. With the environmental security of the site relying on these environmental protec on systems, the geosynthe cs selected must be trusted. Here, geosynthe c solu ons ® include our HDPE geomembrane Carbofol , our GCLs Bentofix and Bentofix X, our nonwoven geotex le Secutex and our reinforcing geogrids Secugrid and Combigrid
Naue has more than 50 years of experience in geosynthe cs development, produc on and installa on. We can be your single point of contact to find a proper solu on for your geotechnical challenges in your mining projects.
BMG's range of NORD aluminium drives is available with the nsd tupH (Sealed Surface Conversion System) an corrosion treatment, which has been developed by NORD DRIVESYSTEMS, for improved process reliability in extreme environmental condi ons and for hygienically cri cal applica ons.
“NORD's nsd tupH surface and corrosion protec on system, which is resistant to acids and alkalis, is a highly efficient an corrosion treatment for gear units, smooth motors, frequency inverters and motor starters in washdown-op mised cast aluminium housings,” explains Derrick Louw, NORD product specialist, Electromechanical Division, BMG.
“BMG's NORD nsd tupH drive units are a robust alterna ve to painted geared motors or Stainless Steel versions. The nsd tupH cataly c surface treatment process permanently bonds a high hardness layer to the aluminium substrate, to offer the same corrosionresistance as Stainless Steel. Advantages include extended surface life, a substan ally lower mass, improved
installa on op ons and cost efficiency
“NORD's easy-to-clean surface treatment is not a coa ng like a paint layer, that can detach or flake off. This durable protec ve layer offers op mum protec on against scratching, blistering and the penetra on of corrosion, even if the unit is damaged. This surface conversion system is highly resistant to extreme environments and aggressive cleaning chemicals, even under high pressure washdown condi ons.”
NORD drives with nsd tupH comply with FDA Title 21 CFR 175.300 and for this reason are suitable for food applica ons. They have been successfully tested according to ASTM D714 (blistering), ASTM D610-08 (corrosion), ASTM D1654-08 according to DIN EN ISO 2409 (scratching), ASTM B117-09 according to DIN EN ISO 9227 (salt spray test) and ASTM D3170 (Gravelometer). In addi on, resistance to common cleaning agents, which are used in the food industry, has been confirmed in tests.
All DIN and standard components for BMG's NORD nsd tupH aluminium drive
units, including drive sha s, are made from Stainless Steel. Fan-less smooth motors, which run quietly, do not spread germs. They are available as synchronous and asynchronous motors and comply with efficiency classes IE2 and IE3 (asynchronous motors) and IE4 (synchronous motors).
Typical applica ons for NORD drives with nsd tupH surface treatment, include the food and beverage industry, bo ling and canning plants, water treatment and sewage plants, as well as offshore and onshore applica ons. This range is suitable for use in any plant that requires a washdown a er produc on.
The NORD range, which is assembled locally by BMG according to stringent interna onal quality and safety specifica ons, has earned recogni on by the local market for reliability, high efficiency, reduced noise levels, extended service life and minimal maintenance requirements.
New to the range of bulk handling systems from BLTWORLD, is the contact-free AirScrape® conveyor belt skir ng system, which significantly reduces material spill, dust forma on and explosion hazards at transfer points and other cri cal sec ons in the conveyor chain.
Because this system hovers freely above the conveyor belt, skirt fric on and belt damage is eliminated and service life is extended.
“The AirScrape system - which encompasses inward facing, hardened-steel diagonal blades - operates according to a new principle where it hovers 1-2 mm, on the le and right side above the conveyor belt. These blades deflect larger par cles inwards, while using the airflow of the conveyor belt and conveyed material to create an inward suc on, flowing any dust and fine par cles back into the product flow,” explains Ken Mouritzen, managing director, BLTWORLD. “Through these diagonally fi ed plates and the speed of the running belt, air is drawn from the outside inwards. As a result, neither the dust nor material can escape.
“Conven onal skir ng is pressed against a
conveyor belt to keep dust and material in the middle of the belt, but a er a period, wear of the skir ng and belt can be so severe, that material and dust escapes. Material spillage at transfer points needs to be removed and regular maintenance of belt skir ng and transfer points is necessary “With the AirScrape dust-free and contactfree, side sealing system for belt conveyors, there is no skirt contact and therefore no belt wear or damage. Motor power requirements are reduced as there is no belt-skirt fric on and because there is con nuous skir ng with no gaps, product loss is minimal.
“Studies show, that even three years a er installa on and with con nuous use in harsh condi ons, the AirScrape system hardly shows any signs of wear. Opera onal costs are also reduced because there is no need for spillage collec on, regular maintenance, or replacement parts.”

Africa is a con nent richly endowed with a variety of economically viable mineral deposits. The con nued discoveries of these mineral deposits have made the con nent a beehive of ac vity in the recent past with mul na onal mining companies seeking to have a piece of the pie.
Heavy Minerals Mining is one of the numerous explora on ac vi es currently being undertaken on the con nent. They are called heavy minerals because they have a
density greater than 2.9 g/cm3. 75 percent of the world's tanium is produced from heavy mineral sands. Various African countries have huge deposits of this mineral with South Africa being the second largest producer of tanium and zircon in the world a er Australia.
Kenya will see its first bulk shipment of tanium minerals come online in January 2014 from Base Titanium's Kwale project while other countries like Namibia,
Mozambique, Senegal, Tanzania, Sierra Leone, Gambia and Mauritania also have heavy mineral poten al.
Heavy mineral sands are an accumula on of valuable minerals, normally called placer deposits, formed by gravity separa on during sedimentary processes.
Upon deposi ng of sand on the coastline by waves heavy minerals are concentrated as backwash carries some of the lighter minerals back to sea. Onshore winds which
preferen ally blow lighter grains inland some mes lead to higher concentra ons of heavy minerals at the front of coastal dunes and as a result strandlines, old fossil shorelines, can now be found a li le distance inland. Heavy mineral sands are an important source of tanium, rare earth elements, thorium, zirconium and tungsten and industrial minerals such as diamond, sapphire, garnet and occasionally gemstones.
Heavy minerals have vital economic applica ons. Even though the strength and chemical inertness of tanium allows it to be used in defense, medical and aerospace industries more than 95 per cent of total tanium supply is for pigment produc on. Zircon is used in TV screens due to its ability
to absorb X-rays. Its hardness, high mel ng point and low expansion coefficient when heated enables it to be used in foundry sand and as an abrasive.
It is also used as a source of zirconia for the chemical industry in adhesives, an perspirants, catalysts, aqueous polymers, gela n hardening and dyes. Zircon is also used mostly in the ceramics industry to glaze finishes of les, crockery and bathware for durability and resistance to discolora on.
As a metal Zirconium is fairly so , malleable and easily worked. Its high density and high mel ng point makes it suitable to be used in modern superconductors. The oxide is also used in fuel cells, transducers in audio equipment and oxygen sensors. In the paper coa ng industry, Zr-carbonate acts as an
insolubilizer while in tex les potassium hexafluorozirconate acts as a flame retardant.
Heavy mineral mining has both economic and social benefits to the host countries. Mining of these minerals creates employment for thousands of ci zenry. This significantly improves the social status of the people in the third world countries. It also leads to development of various infrastructure projects such as roads, ports, dams e.t.c. An ideal example of how these mining ac vi es can benefit the local people and play an important role in advancing the na onal economy well beyond the life of the mining opera on is Base's Kwale project in Kenya.
There is a direct correla on between the market size of contract mining and the commodi es cycle/prices and investment pa erns in capital projects Historically, mining was a highly protected industry and had a low propensity for outsourcing, but more opera ons are being outsourced across Africa, says global consultant and adviser Deloi e.
This is owing to mines not having access to robust mining systems and processes, exper se and the ability to control the en re mining value chain, limi ng the realisa on of a project's opera onal poten al, asserts Deloi e associate director Mahendra Dedasaniya. “There is a direct correla on between the market size of contract mining and the commodi es cycle/prices and investment pa erns in capital projects.
Amid current market condi ons, many mining opera ons have started to consider outsourcing part of or all their opera ons to the best contractor to achieve the best
cost and produc vity possible,” Dedasaniya comments. He notes that using contractbased mining services is a strategic, longterm decision and must be integrated into a mining company's business and opera onal strategy to achieve the best possible outcome.
Contract mining is used not only to implement rapid strategic change but also to assist in providing a compe ve edge in the global market, Dedasaniya points out. He illustrates that many mining companies in South Africa, Namibia, Botswana, the Democra c Republic of Congo and Zambia have outsourced their mining opera ons, such as Kimberley Diamonds, Kalagadi Manganese and Langer Heinrich, as well as the zinc mines of Black Mountain.
The decision to outsource is normally based on opera onal cost, capital efficiency, flexibility, rela onship and competency, as well as the owner's current status in terms of the age of the fleet, required skills availability, produc vity,
overhead cost, the type of mining opera ons and the mining method employed, Dedasaniya adds.
He emphasises that, when considering outsourcing mining services, it is important to weigh the organisa on's op ons in terms of the type of contract, selec on of the right contractor and the measurable output requirements while balancing socioeconomic considera ons. The selec on of a contractor should be based on their past safety sta s cs, alignment with business and corporate strategy, shared values and cultural fit, as well as understanding the poten al risks associated with contract mining and the probability of mi ga ng these risks based on actual requirements.
He puts forward that selec ng the right business partner, in terms of the type and form of contract, will result in defining balanced commercial terms involving the
incen ve of shared benefits between owner and contractor and flexibility with regard to changing the contract scope. In terms of output control, Dedasaniya says defining the mining company's objec ves and goals in terms of outsourcing plays an important role in ensuring that the contractor will be able to perform accordingly. He notes that by defining the dependencies that other opera ons could have on a contractor's performance and how to reduce this reliance when output is at risk, will also assist in preparing recovery plans. “Once you enter into a contract, it's very difficult to exit without disturbing opera ons. It is, therefore, of great importance to chose the right business partner who shares a company's values and envisions the same end goal,” he declares.
Dedasaniya asserts that there are various models available when selec ng contractors that will best meet the requirements of a project and those of a company. These models can be iden fied as full outsourcing or par al outsourcing models, he says, explaining that full outsourcing includes all project needs such
as equipment, labour, materials and infrastructure. Par al outsourcing is when the equipment and infrastructure is supplied by the owner, with the contractor supplying labour and, at mes, maintaining equipment.
Dedasaniya notes that, if outsourced mining is not part of a business's opera onal plans, it could result in the cost of mining being higher by as much as 15% to 20%, adding that there could also be a loss of intellectual property since there is no con nuity in knowledge, which ul mately affects the decision-making process. Therefore, should the contract be prematurely terminated, the en re opera ons cycle will be disrupted, resul ng in revenue loss. He also notes that an inadequately defined scope and responsibility matrix leads to conflict and unhealthy rela ons between the par es, affec ng the targeted outcome of the outsourcing business case.
Dedasaniya highlights that, when contract criteria are met and the best model has been selected for an opera on, outsourcing
has many advantages, such as the achievement of produc on targets within budget and on schedule. Addi onally, he says contracts can also be structured to allow for opera onal costs to be converted from fixed costs into variable costs during mes of low produc on volumes, reducing the risk of nega ve profit margins.
“The mining environment has an influence on many variables, such as ground condi ons and market condi ons, which some mes erodes the business case; however, outsourcing provides flexibility and scalability in [a mining company's] model to meet ever-changing produc on requirements, resul ng in a smooth transi on between mining methods such as openpit to underground mining.”
Dedasaniya points out that the effec ve use of resources and the deputa on of a subject-ma er expert from one opera on to another is also an added advantage. “Outsourcing should emphasise and create bonds and networking in an organisa on to ensure it achieves the best possible produc on at the pre-agreed produc on cost, while achieving higher capital efficiency and flexibility [at] mining opera ons,” concludes Dedasaniya.

IF “GREED” WAS THE BUZZWORD 20 YEARS AGO, one could argue that today it is “choice.” In choice, there is power
When our founder, Jerry Dyess, had the vision for Choose Energy, his goal was to demys fy the u li es business for the average consumer. Quite simply, energy is a commodity and a need. And, the more choices, the be er it is for everyone involved. Tradi onal retail companies have long thrived by providing consumers with op ons. The prolifera on of online marketplaces has given consumers the ability to make smart choices and save money on everything from car insurance to healthcare. However, un l recently, consumers didn't have a choice when it came to energy – one of the few things that they literally can't live without. In states where energy deregula on is becoming more and more prevalent as it has in other countries, many of the consumers in these states either do not know that they have op ons, and if they are aware, they likely do not know what or how to choose. That is where the power of the energy marketplace comes in.
At Choose Energy, we not only provide the online pla orm to purchase the commodity
of energy, but we act as a connector and facilitator, allowing customers to compare and shop for their electric, natural gas and other energy providers. Energy marketplaces provide consumers the ability to see all of the energy supplier's offers in one convenient place so they can compare one offer with another, side by side. O en these same consumers receive offers from energy companies that sound like a good deal but there is no way for them to compare the costs or the benefits with alterna ve op ons. We help them find the right place and the right planwhether they are looking for a fixed plan, a shor erm op on, cost savings or a greener choice. Finally, the consumer doesn't have to blindly pay their energy bill and feel like they have no choice when it comes to the provider who keeps their lights and their heat on.
We also help the energy suppliers communicate their services through a trustworthy pla orm so they can a ract and retain the right consumers. Suppliers now are compe ng for the customer's business, which puts the consumer in the driver's seat. Energy marketplaces benefit the consumer
and the provider, by offering services such as comparison, transparency, ease of enrollment and strong customer service while guiding consumers through the decision-making process of comparing and/or switching suppliers. Imagine 20 years ago – even 10 –being able to go online and shop for energy needs. We are currently in eight deregulated electricity states and just announced in January that we have expanded into six deregulated natural gas states, with plans to launch our services in three more states this month.
Educa on is a key factor in the expansion of energy choices and the deregula on process. In deregulated energy states in the United States (in which more than half the U.S. popula on lives), once consumers were given a choice in energy providers, they may have found themselves overwhelmed with monthly mail inserts, door hangers, or mul level marke ng agents ringing doorbells and phones. These channels were the only op on the energy companies had – but now retail energy suppliers are reviewing their marke ng budget alloca ons and realizing that the changes in regula on have brought new op ons and new marke ng channels,
Since energy is a commodity and a need, more choices are better for all parties in the industry
which benefit them.
This complexity behind the energy sales and marke ng processes create confusion for the consumer, and is the reason that educa on is paramount. In addi on, educa on varies by market. For example, Texas, Pennsylvania, Connec cut and Illinois have reached greater than 50 percent deregulated electricity market adop on over the past few years. There is currently more educa on in these deregulated states on electricity op ons, so we are building on that awareness to inform consumers that natural gas choices are also available. One of the great things about Choose Energy is that people can switch electricity and natural gas in one place, at one me (in states where available).
With this winter's energy bills substan ally higher due to the much-reported “Polar
Vortex” and other weather extremes across the country – consumers are paying more a en on to their energy bills.
Many states are also experiencing rate hike announcements, so we expect more and more consumers to take control of their energy op ons. Choose Energy is growing over 100 percent a year in all of our markets. While cost is important, energy choices aren't limited to price. Some consumers have made the decision to change providers because they want a renewable plan as part of the “green movement.” Un l fairly recently, renewable choices were challenging for consumers to access. Today, up to 20 percent of Choose Energy's customers have chosen offerings that come from renewable sources. While not always the least expensive, it is perfect for those who are commi ed to
making environmentally conscious shopping decisions.
Others are searching for the best price or a way to manage their budgets, removing the risk of energy price increases. The typical consumer in a deregulated market can save as much as much 25 percent on their yearly energy bill.
This is truly a game changer for the u li es business. Deregula on has provided people with the ability to choose energy providers. With the pla orm to pair the consumer with the provider based on their individual needs down to the details of region, climate, psychographics, demographics, economics and priori es – energy marketplaces have the power to personalize that choice.
With over 20 years of experience in the field, EGI Industries has a department that specializes in automated applica on of thermal coa ngs to extend the life of cri cal industrial mechanical parts. EGI Industries serves various types of industries at all stages from prototyping to high-volume parts produc on. EGI Industries acquired an ultra modern thermal spray system that builds coa ngs with excep onal proper es. We are equipped with a metallography laboratory to
In addi on, EGI Industries', services are based on internal and external R&D to create, improve and develop processes that serve to provide solu ons tailored to the needs of each and every client. It is also one way in which we respect one of our biggest corporate values: being open to innova on. With machining and finishing, EGI Industries offers turnkey solu ons for all of your failing,
and wearing parts inside your equipment. Our process is quite unique. Clients in various industries mostly all experience parts and equipment failures such as valves, pumps, air locks, sha s and so forth; all of which could not withstand either the chemicals being used, temperature or abrasive materials they are in contact with. Replacing parts, and equipment is extremely costly and not forge ng the cri cal and expensive down me that is incurred.
Valves/Pumps are an example, which are commonly found in mine sites all around the world. Certain makes and models can cost within the range of tens to hundreds of thousands of dollars. These name brand valves do not always have an -wear coa ngs, which is needed to withstand the abrasive chemicals passing through. We rebuild all makes, models, and sizes for valves/pump housings and other components back to the original manufacturers' specifica ons at a frac on of the cost for a new replacement. Our warrantee backs all of our parts and work.
As solu on experts, our goals are to produce the longest las ng parts with excep onal quality. We customize every gear, pinion, and gearbox internals with the best steeltreatments currently available. We cer fy every gear and gearbox refurbishment/upgrade with test bench reports and include a warranty to our clients assuring them they're well taken care of. We teach our clients that many gears may look similar; however, looks are deceiving to the untrained eye. Gear steel quality, origin of the steel, treatments perhaps used, chemical composi on before and a er treatments, and overall strength all are ponderous factors to
be considered when bearing in mind the reliability of your gears inside your crucial equipment. Higher quality generally means higher price-per-item. Clients looking only at price sa sfying their budget numbers unfortunately discover catastrophic and/or even premature failure that ends up cos ng the plant numerous hours or days of costly down me. This unacceptable predicament is one we simply cannot stand for and we will do everything in our power to prevent our clients from falling vic m to it. It may be simple and fast to cut corners and produce inferior components; however, at EGI, you will never need to worry about that; guaranteed.

Fibertex geosynthe c solu ons for road maintenance, include Fibertex AM-2, which is a flexible needle punched nonwoven paving fabric. This robust product, was specifically developed by Fibertex, for African road engineering condi ons.
“The func ons of Fibertex AM-2 are twofold: To avoid reflec ve cracking of new asphalt. This material is used to prevent the propaga on of cracking from an old pavement surface being transferred into a new re-sealed surface - stress relief,” says Lionel Kistan, export sales manager, Fibertex South Africa –manufacturers of geosynthe c products.
“The second func on of Fibertex AM-2 is to protect the subsoil from water intrusion and thereby loss of bearing capacity. In this case it is used to create an impermeable membrane layer – a seal - to prevent the ingress of surface water into road layer works through exis ng cracks in the pavement.
“When water saturates the load bearing layers under a road surface, the bearing capacity of such layers reduce and crack forma ons could eventually propagate and lead to pothole forma on under the dynamic loads of heavy traffic.
“This membrane also act as a Stress
Absorbing Membrane Interlayer (SAMI) to prevent surface stress cracking by absorbing stresses imposed by differen al loads.”
The Fibertex AM-2 system can be applied mechanically for large volume installa ons, as well as manually in cases where narrow width installa ons are required. By using Fibertex AM-2 paving fabric in road maintenance projects, future maintenance cycles can be reduced; full road rehabilita on projects can be postponed and pavement life can be extended, which means substan al cost savings.
Addi onally, when using Fibertex F-grade geotex les in a basal separa on applica on below the road prism, the road design can be adjusted to decrease the thickness of load bearing layers, while s ll maintaining or even increasing its load bearing capacity. This results in a more cost effec ve design. Alterna vely, without the use of a separa on fabric in weak subgrade condi ons, punching of engineered aggregate into the weak subgrade could occur, as well as ingress of the below subgrade into the engineered fill material. As a result, the bearing capacity of the base course could be reduced over me, which could lead to basal failure of the road. Virgin PP geotex les have a high level of chemical stability over a wide pH range and are thus suitable for applica on in most civil engineering environmental condi ons. This characteris c ensures its durability, where product failure might not only impact on project cost, but could have a long term environmental impact.
Fibertex UV stabilised virgin PP geotex les are the only nonwoven geotex les produced in Africa with cer fica on for durability of over 100 years, in accordance with the latest EN standards.
This range of environmentally-friendly geosynthe c materials encompasses nonwoven and woven geotex les, gabions and ma resses, drainage pipes and fi ngs and erosion control and cellular confinement solu ons. The company also supplies soil reinforcement and stabilisa on products, including geogrids and geocells, as well as geosynthe c clay liners (GCL) and geomembranes (GMB) that can be used as part of composite lining systems in waste containment solu ons.
Fibertex South Africa's team of experts from branches in KwaZulu-Natal, Gauteng and the Western Cape offers a technical advisory and support service, to ensure correct specifica on of durable and safe materials for every project.
