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.
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.

Over the years, sonic drilling has con nued to evolve, with improvements in vibra on frequency, power output, and drill bit design. Today, sonic drilling is a widely used technique for a range of drilling applica ons, from mineral explora on and geotechnical surveys to environmental monitoring and geothermal energy produc on Its advantages over conven onal drilling methods include faster drilling rates, reduced waste material, and be ercorerecoveryrates.
Sonic drilling is par cularly effec ve in so er materials such as clay and sand, which can be difficult to drill using tradi onal rotary core drilling methods. The sonic drill head allows the soil sample to enter the single tube core barrel by liquefying the ground on the sidewall ofthesampleenteringthecorebarrel,without disturbing the sample, thus providing very good core recoveries in the so er more friable ground in which is tradi onally more difficult to provide good core samples Sample
recoveries using sonic technology are usually over95%.
To date, the GeoGroup is a preferred supplier of sonic drilling services to the African con nent.Outofthe3Sonicrigsintheirfleet,2 of these rigs are equipped with dual head masts able to switch between sonic and rotary core drilling. This eliminates the need to have mul ple rigs on site as the mast head can quickly transi on between Sonic and Rotary core.
The GeoGroup recently introduced the Secon Compact Sonic Crawler 190kN to their por olio which can be operated remotely by two drill operators with wireless controllers. Using a wireless control system to operate a drill has several advantages over tradi onal wired controls. Here are some reasons why wirelesscontrolmaybepreferred:
1
Mobility and flexibility:With a wireless control system, the operator can move around the drilling site more freely, without being tetheredtoacontrolpanelorconsole.Thiscan be par cularly useful in drilling projects where the operator needs to move around the rig to access different drilling loca ons or perform othertasks.
2
Increased safety: By elimina ng the need for cables and wires, wireless control systems can reduce the risk of accidents and injuries caused by tripping over cablesorge ngtangledinwires.Thiscan be especially important in drilling projectswheresafetyisatoppriority.
3 .
Improved efficiency: With a wireless control system, the operator can control

the drill from a distance, which can be more efficient and faster than manually adjus ng controls at the drill site. Addi onally, some wireless control systems offer advanced features such as automa on and remote monitoring, which can further improve efficiency and produc vity
Overall, sonic drilling is a versa le drilling methodthatcanbeusedinawiderangeofsoil and rock forma ons. Its efficiency makes it a popularchoiceformanydrillingprojects.

Clamp-on flow measurement using the ultrasonic transit me technique has matured and is now a preferable technology for control and monitoring in many metallurgical and mining applica ons. In general, if any two of the following are present then Ultrasonic Clamp On (USCO) should be considered or even preferred.
We at Flexim, as the leader in this field has seen an increase in requests par cularly in the following areas:
Water monitoring and stewardship
Mines and minerals use water in various ways, from high pressure hydro power lines
in underground mines to drive drilling equipment, to a solvent in hydrometallurgical opera ons to dust suppression, the common denominator is a requirement to responsibly and efficiently use and account for the water to do the least harm to the environment and nearby communi es. Flexim's rugged portable meters are ideal for audits and repor ng while the fixed meters are in many cases be er suited than the tradi onal mag meter
SO Abatement 2
Sulphuric acid produc on as a method to reduce SO emissions is increasingly 2
becoming a preferred route to reduce this pollutant. The benefits are no addi onal waste streams, a saleable product and, depending on the technology, low addi onal water and other input requirements. A unique feature of metallurgical SO fed 2 Sulphuric acid plants is the fluctua on of the feed SO concentra ons and the resul ng 2 affect it has on the stable opera on of the plant. Flexim meters are an ideal solu on as they can be retrofi ed with no shutdown (no fines or risk to equipment during start up) give both flow and concentra on measurement and work on both metal and GRP pipes. “We have recently installed meters on plants in Zambia, the DRC, South
Africa and Namibia”, says Mark Middelhoven the Africa Sales Manager, and all our customers have seen improvement in their plant performance.
SX circuits both water and hydrocarbon mediums and USCO is a good measurement technique as it can measure both phases. Typically these are installed on the organic side, recently Flexim has been involved in a project to provide metering on SX cells as part of an automa on project. Previously this had been done by manually adjus ng the valves, but as the trend to more automa on
and reduced personnel con nues the need to automa on and the benefits of be er control and efficiency the scope and usefulness of USCO is a key enabler
As the world moves towards a Net Zero future mining is key both in reducing its carbon emissions but also providing the raw materials for ba eries, electrical infrastructure and catalysts for hydrogen produc on. It is not surprise then the mines are inves ng in improving their energy efficiency. Flexim again can help whether it is measuring steam in the processing plants or
compressed air, addi onal metering points can be safely added hassle free.
One aspect holding back the adop on of Clamp-on is previous bad experience, either through cheap portables or incorrect specifica on. Since the meters are able to be installed outside the pipe, with no interrup on, it is easy to de-risk the decision through a trial or demonstra on. At Flexim we are happy to stand behind our product and a try before you buy approach is usually enough to convince scep cal stakeholders. The technology has matured and should be the first choice of technology in many instances.
The Tailings Recovery System (TRS) is a technology developed specifically for recovering tailings from mine tailings pond deposits, to facilitate tailings pond reclaim opera ons and management of tailings storage facili es within an opera ng mine site. TRS can also be u lized for the remedia on of legacy tailings ponds, and reprocessing mine tailings to extract valuable minerals.
TRS has been developed by Technika Engineering Ltd., a company based in Calgary, AB, Canada.
TRS effec vely addresses the opera ng limita ons of the technologies tradi onally u lized for mine tailings reclaim opera ons, including CSD dredges and submersible pumps. The limita ons of these technologies include inconsistent tailings supply density and the need for frequent reloca on on the pond. Dredging causes high turbidity of the pond surface water, which is o en reclaimed
for the process requirements. Dredges and pumps are suscep ble to plugging by various debris that is commonly found in tailings deposits.
Dredging is a crewed opera on requiring people to be deployed on the pond, and may also be affected by seasonal weather condi ons.
TRS technology is an unmanned, remotely controlled opera on. Its control can be effec vely integrated into the overall control system of the tailings treatment facili es, which enables the supply of tailings at a density and flow rate that is op mum for the performance of the tailings treatment processes.
TRS can operate from a single loca on for an extended period of me without a need to relocate.
TRS opera on is based on a balance of parameters that include its geometry, tailings rheology and recovery rate. The opera on of the technology is based on the principles of the hydraulic pressure balance within the tailings pond deposits and the TRS caisson structure. The opera ng interface between TRS and tailings deposits effec vely mobilizes the tailings within the pond deposits crea ng the tailings draw zone. The mobilized tailings are brought to the surface within the TRS caisson envelope.
The tailings of the required density are
accessible from the surface for collec ng and transport to the shore-based facili es.
The TRS caisson typically comprises two telescoping shells that allow easy adjustment of the pumping depth. The telescoping shells can be elevated to facilitate the system's launching, deployment, and reloca on.
The TRS assembly is of a modular design. The modules, which are designed to fit shipping envelopes, facilitate transporta on and minimize me to assemble the system onsite. This also enables easy reloca ons between different tailings ponds or the mine sites.
An ini al set of TRS units was developed by the Technika Engineering team and successfully deployed in large-scale tailings recovery opera ons in the Canadian oil sands industry
The Company is now looking for opportuni es to expand into other mining areas where the TRS technology can provide a valuable contribu on to mine tailings reclaim and tailings management opera ons.
The TRS technology is patented and proprietary to Technika Engineering Ltd. For addi onal informa on, please visit h ps://wwwtechnikaeng.com/technology/tailings-recoverysystem-trs.html

At Nilfisk, we have a clear mission that drives our dedica on in what we do: we enable sustainable cleaning worldwide to improve quality of life. For more than a 100 years, we have been commi ed to making the world a cleaner place. Nilfisk South Africa markets a wide range of pressure washers for a number of applica ons.
Pressure washers are the most effec ve way to clean outdoors and are extremely easy to use: connect the device to the water supply and power outlet, turn on the tap, switch on the pressure washer and let the cleaning begin! With added accessories, the devices are transformed into real all-rounders, the applica on possibili es are virtually unlimited. Typical areas of usage for the machines include cleaning applica ons in the agricultural, construc on, earth moving field, mining and heavy engineering industries. Nilfisk boast the most comprehensive range of pressure washers, namely the MC range, the MH range and the WAP range. The local range consists of the Novastar, Powerstar, Jetstar, Topstar, Centra, Electra and HPU which are medium and heavy duty pressure washers. Outside of this range we also manufacture purpose built units specific to applica on. Although many applica ons
require portable units, we also produce sta onary units for wash bay and other similar applica ons.
The WAP range both mobile and sta onary have their components mounted on a sturdy steel base frame, protected by a steel impact protec on cage. The high pressure pump is directly coupled to a standard speed electric motor. The machines have a sturdy steel chassis with roll cage for maximum component protec on, as well as easy loading and off-loading. Opera on of all the machines is controlled from a “trigger” type safety spray lance.
The Nilfisk MH series takes mid-range hot water high pressure washers to a new level. As the powerful engines provide pump pressures of up to 220 Bar, and the improved EcoPower boiler system offers high efficiency whilst saving both the environment and fuel costs - leaving our customers with an improved total cost of ownership. These high pressure washers are developed for our customers within agriculture, automo ve, light industry, trade and building and construc on. These businesses, with many daily cleaning tasks, will benefit from the highly improved and best-in-class mobile design enabling them to transport and move
the machines around their facili es and giving them the mobility to work anywhere. From light industrial cleaning tasks to slightly heavier cleaning applica ons in rough environments, ba ling anything from mud, animal manure to road dirt, oils and greases. The Nilfisk MC range of compact cold water high pressure washers offers customers the benefits of reduced running costs, greater cleaning efficiency and easier overall handling for general everyday cleaning tasks. They offer superior cleaning results, saved me and lower costs.
With the MC range, Nilfisk is introducing three major improvements to the high pressure cold water range: Detergents are now supplied more effec vely through a new separate foam sprayer system. At the same me, a new patented spray gun holder adds convenience together with a new turnable cable hook. They are the ideal choice for small building companies, light agriculture such as small crop and milk farms. The choice of “the correct” pressure washer unit is always determined by the applica on, availability of power and water, as well as frequency of cleaning required.

When we talk about magnetometry with drones, we must consider the challenges presented by the applica on of this geophysical method. When moun ng a magnetometer on a drone, either total range or fluxgate, we find electrical components, magne c materials, even the movement of the drone motors, which generate magne c ac vity that can easily cause altera ons in the acquisi on of data, preven ng accurate and useful results for the regional characteriza on of mineral resources.
The search for minerals with high magne te content such as iron or nickel, are the ideal scenario for this type of applica ons, however, the search for high value nonmagne c minerals such as gold and silver, find great benefits through the applica on of geophysical methods such as magnetometry with drones.
Therefore, our applica on for the mining sector focuses on the regional characteriza on of magne c ac vity, this means that we generate maps of magne c ac vity of large extensions, adap ng to the topography of the terrain and allowing its correct measurement despite topographic changes, at mid-en high al tudes flights, and obtaining more accurate readings for its interpreta on; a ma er in which most of the magnetometers that currently exist in the market are more limited. In this way we generate informa on that allows us to make a punctual explora on planning, in a short period of me and with completely accessible costs.
Currently, we can inspect up to 600 hectares per day with a single opera on team and its processing and interpreta on, in addi on, with our data cleaning so ware we can deliver results in a ma er of days. To date, AV3 AEROVISUAL has taken this solu on to different parts of Mexico and La n America, having generated maps of magne c ac vity over surfaces of thousands of hectares in

defini on to further delimit the explora on area or even, to apply other complementary geophysical methods such as AMT (audio magneto-telluric) soundings and gravimetry, to obtain greater certainty of the viable zones for explora on and extrac on of resources, besides giving the possibility of genera ng
robust and reliable models for the planning and defini on of zones of interest.
To solve the challenges posed by the applica on of this geophysical method, since 2014 in AV3 AEROVISUAL the design and manufacture of the equipment we use today was carried out through the Na onal Autonomous University of Mexico and the "Laboratory for Electromagne c Innova ons" of Ukraine, specialized in the manufacture of magnetometers and electronics for satellites. Currently, we have developed two versions of fluxgate magnetometers with the capacity to perform independent measurements in the 3 components (X, Y and Z) in addi on to measuring their geoposi oning, date, me, inclina on and other essen al measurements for a correct interpreta on of data. Likewise, these equipment have a design that eliminates the magne c interference that the drone generates on them. To ensure the inclina on and posi on of the magnetometer during the flight, a non-magne c stabilizer was designed and implemented that allows us to move the magnetometer up to 3 meters away from the drone; this stabilizer allows us to keep the sensor ver cal with respect to the ground, in this way the wind trac on and drag by the movement of the drone during the flight, does not generate loss or need to remove data not useful for interpreta on, resul ng in reliable informa on of great value for decision making.

Mining engineers design safe and efficient mines for removing coal and metals. Mining engineers op mize mines for removing resources in the most efficient manner possible. They ensure that the as much of the resource as possible is extracted.
Mining engineers o en specialize in a par cular mineral or metal, such as iron or coal. Some collaborate with geologists to find and evaluate new ore deposits. Others develop or improve mining equipment, or manage processing opera ons that separate and refine minerals. Mining safety engineers implement best prac ces, conduct mine and equipment inspec ons, monitor air quality, and ensure compliance with all safety regula ons to keep workers safe.
With the process of mineral extrac on, some amount of waste and uneconomic material are generated which are the primary source of pollu on in the vicinity of mines. Mining ac vi es by their nature cause a disturbance of the natural environment in and around which the minerals are located. Mining engineers must therefore be concerned not only with the produc on and processing of mineral commodi es, but also with the mi ga on of damage to the environment
both during and a er mining as a result of the change in the mining area.
Mining engineers plan and direct the various engineering aspects of extrac ng minerals from the earth. They prepare ini al plans for the type, size, loca on and construc on of open pit or underground mines
Mining Engineer - Open Pit .
Mining Engineers working in open pits are involved with both long and short term open pit mine planning, mine design scheduling and budge ng, strategic planning, supervision of technical and opera ng staff, mine management. They are also involved with feasibility studies, drilling and blas ng supervision, opera on of mining systems, evalua on of open pit mining equipment, mining contract development.
Mining Engineer - Underground
Underground Mining Engineers can be involved with coordina ng mining ac vi es, maintenance scheduling for all equipment, short/ long term mine planning, scheduling and design. They supervise staff and are involved with feasibility studies, mining
contract development, design opera on and maintenance of underground mining equipment.
Mining Engineer – Coal
Coal mines can be open pit or underground and tend to use different mining methods. Coal mines can be prone to gas and fire problems. Coal Mining Engineers can be involved with coordina ng mining ac vi es, maintenance scheduling for all equipment, short/long term mine planning, scheduling and design. They supervise staff and are involved with feasibility studies, mining contract development, design opera on and maintenance of mining equipment.
Mining Engineer - Consul ng Mining
Engineers who work as consultants are o en involved in a wide variety of projects, mining methods and different technical areas. They use computer programs to model the mining process and design and can work on both open pit and underground developments. Consul ng mining engineers will typically be based in coastal ci es and fly out to projects and mines as required.
