Digging deeper into quarries Digging deeper into quarries
“
What is the difference between a quarry and mine,” is a question that is often asked by members of the public (even mining industry professionals) when seeking clarity on aspects of the law that affects these operations. The answer is that in South Africa quarrying activities to extract sand and aggregates fall under the same legislation as any other mining activity and therefore operators need to adhere to the same legal framework. Although the minerals or materials being mined have vastly different values and require altogether different skills-sets to extract them from the ground, the basic principals remain the same. The rules of engagement are also the same as are the channels used to apply the law. Essential minerals Although less glamorous than diamond, platinum, gold and other mineral mines, Quarries in South Africa, especially aggregate and sand operations, are essential sources of materials from which concrete and asphalt aggregates are extracted. These are used to construct roads, railways, pipelines, dams, buildings, houses and many other infrastructural needs. In years gone by the unregulated proclamtion and gung-ho management of quarries often
2
led to conflict with communities and authorities alike and when depleted the open excavations were left to scar the environment. Natural habitats and waterways were often destroyed and illmanaged human resources more often than not led to workers being poorly treated and surrounding communities feeling aggrieved towards these operations. However, since the establishment of Aspasa and the drive to professionalise the industry, more than a decade ago, the quarrying industry has cleaned-up its act. Aspasa members now abide by the Mineral Petroleum Resources Development (MPRD) Act and undergo annual audits to ensure compliance with health, safety, quality and environment requirements of the association, as well as legal requirements. Leading by example The association in its owns capacity belongs to the Chamber of Mines and has become a key role player in the industry and plays leadership roles in a number of key areas such as, preventing illegal mining, stopping unsafe practices on quarries (mines) etc. Although quarries are separately legislated in other parts of the world, the decision to “lump” all extractive operations together makes sense , especially as far as enforcement is concerned. “Through Aspasa the quarrying industry has found its voice and we continue to work towards establishing our quarries as safe, environmentally
sound and sustainable “mining” operations. “As with any such operation, in cases where members of the public or surrounding communities have a complaint about a quarry, we suggest that the complaint be taken up with the quarry manager and formally lodged with the company. Most professional companies will be members of Aspasa and should remedy the situation in a professional manner. Finding solutions “The problem however comes in where illegal and unregistered quarries are involved. In these instances, it is best to escalate the issue to actually laying charges at the local police station. Simultaneously, to report the matter to the Department of Mineral Resources and the Department of Environmental Affairs. “It is advisable that companies and individuals take a stand and do not let any illegal, unsafe or environmentally damaging mining take place in their vicinity. Get the local media involved and bring the problem to the attention of the broader public and take a stand to prevent harm to people and the surrounds.” Nico concludes that although quarries and mines are regarded as the same type of operation in South Africa, the kind of clients and end users are different and Aspasa is there to assist with issues relating to quarries.

250 and TX4-300 units are rated at 165 HP at 2 000 rpm for heavy duty industrial applications and the rated capacity for the TX4-360 is 190 HP at 2 200 rpm. These machines maintain their rated capacity, even at the full steer position. Taylor low emission engines are tier certified, with lower fan and engine speeds for reduced noise levels. There are electronic diagnostics on the engine with a fault code history for fast problem location and a built in emergency shutdown system for the engine and transmission is
standard. more blt-taylorTX4-forklifts-harshconditions…two An engine mounted sealed fan shroud ensures maximum air flow and a seven-blade pusher fan blows dust and debris away from the operator. These robust forklifts have a heavy duty fourspeed powershift transmission with a high capacity 12 plate clutch system for enhanced durability. Other features include a full directional modulation for soft directional changes and operator controlled air inching for precise vehicle positioning in any environment. A high capacity transmission oil cooler is part of the bolted three section cooling system. The cooler has wide fin spacing which reduces dirt build-up and provides efficient engine cooling for dependable operation in all conditions. A dual element air cleaner with a restriction indicator system offers engine protection and a remote mounted filter reduces oil spills. An exhaust purifier system is an optional environmental feature. The fuel tank has a heavy gauge steel wall, with an integral strainer and lockable fuel cap. The newly designed fuel sensor has no moving parts. For improved safety and visibility, the air snorkel and shielded exhausted are mounted on the corners of the cab for a clear view open for the
operator. Dual panoramic interior rear view mirrors and external side mirrors are standard. Other safety features include overhead rear work lights, forward and reverse activated alarms, as well as safety rails and anti-slip steps. Axle mounted spring-on, hydraulic-off parking brakes, with a brake saver system, prevent the operator from driving through the parking brakes. Pedestrian cameras and monitors are optional. To facilitate easy maintenance, the TX4 series has a forward tilting cab and a pivoting chassis for access to internal components. A sliding engine hood with swing away doors on both sides provide access to the engine, filters and dipsticks. Brakes are easily serviceable without the need for axle disassembly. Re-set circuit breakers are used throughout the truck instead of conventional fuses. For easy identification, all wiring is colour and number coded. Frame channels ensure clean and protected routing of wiring and hoses. A frame bar can be placed between the articulated sections for transportation or servicing. blt-taylorTX4-forklifts-harsh-conditions…three The TXB's ergonomically designed, uncluttered operator station is one of the most spacious allsteel cabs in the industry. Features include increased leg and head room, an adjustable arm rest and sound insulation. A vinyl or cloth mechanical suspension seat rotates 15° left and 20° right. Air-conditioning is optional. An adjustable fingertip electric joystick control on the hinge-down instrument panel ensures smooth and precise handling. Steering on a tilt steering wheel is fully hydrostatic. There are two brake pedals – the left pedal controls both brake and inching and the right pedal is for brakes only. The Taylor range of materials handling equipment is distributed exclusively throughout Africa by BLT SA, which solves materials handling requirements by providing a custom machine design service and the supply of specialised attachments to cope with exact tasks.

Ruukki Metals Metals opts opts in in favour favour of of Loesche Loesche mills mills for for Ruukki more efficient efficient steel steel production production more
T
he Finish steel producer Ruukki Metals is converting its blast furnaces at the Raahe site in Finland from oil injectors to more cost-efficient Pulverized Coal Injection (PCI). The new injection system is supplied by Claudius Peters Projects GmbH and two LOESCHE mills LM 23.2 D will be installed to handle the coal grinding. In steel production it makes more sense to reduce the consumption of expensive coke in the blast furnace through the injection of more cost effective reducing agent. Pulverized coal is a significantly more economical alternative to oil here, but without a negative effect on the CO2 balance. With the conversion to a cost-efficient PCI solution, Ruukki is boosting its competitiveness on the price-sensitive world market. Two LOESCHE mills type LM 23.2 D form part of the new plants. The production rate of the mills is 33 t/h at a fineness of 20% > 0.09 mm and a gearbox capacity of 460kW. A variety of special customer wishes were considered when engineering the plants and LOESCHE GmbH delivered within the ambitious time schedule. The plants are expected to go into operation in the third quarter of 2015 with a delivery period of eight months. Claudius Peters Projects GmbH, a specialist in processing engineering in the cement, coal, aluminum, gypsum and bulk produce industry, has long-standing business relations with LOESCHE GmbH. The company is both a customer and a supplier for components like dust pumps, silos and silo systems or two-way gates. As early as 2008,
10
a mill type LM 28.3 D was already ordered for the PCI plant at the ILVA steelworks in Taranto, Italy. Thanks to the positive experience of the technology and price- performance ratio, Claudius Peters has opted for a solution from LOESCHE this time as well, a choice that meets the product preference of the end customer Ruukki.
About Loesche Loesche is an owner-managed, export-oriented company, which was founded in Berlin in 1906. Today, the company operates from its head office in D端sseldorf and has subsidiaries, representativ es and agencies around the world. In 1928 that Loesche built the first spring-loaded air-flow mills, which even today are still known as
Loesche mills. Nowadays, Loesche vertical mills form the core of many plants used to dry-grind coal, cement raw materials, granulated slag, industrial minerals and ores. Thanks to its grinding plants with throughputs of 2 to 300 t/h for the cement industry and self-inert, central coal-grinding plants for hard and brown coal power stations, Loesche is the global market leader for vertical mills and turnkey grinding mills. Loesche supplies turnkey plants, which are individually planned and built for the required process steps. This includes plants for processing, material storage, transportation and delivery, vertical mills, hot-gas generators, filter and separator systems, complete automation technology, plants for all aspects of construction above and below ground, steel construction and piping systems. The company has EN ISO 9001 certification and the grinding plants themselves are compliant with national and international safety regulations. At present, around 330 people are employed at the company's head office in D端sseldorf, with around 600 employed worldwide.
HPE Africa's range of crushing and screening equipment. hpe-africa-crushing&screeningequipment…one High Power Equipment Africa - HPE Africa distributes a wide range of earthmoving equipment, which includes mobile crushing and screening units, as well as hydraulic hammers and drills. “MB crusher buckets, McCloskey mobile crushing and screening plants and Soosan hydraulic hammers and drills, available exclusively in Southern Africa from HPE Africa, ensure efficient performance and extended service life in harsh operating conditions,” says Dave Davel, product specialist, HPE Africa. “This robust crushing and screening equipment is suitable for small, medium and large scale projects in mining, quarrying, construction, demolition, recycling and agriculture.” MB jaw action crusher buckets are designed for on-site crushing of inert materials and unlike other crusher buckets on the market,
12
this range is also able to process and crush material containing rebar steel. Iron separators efficiently divide various iron elements, including concrete and steel, during the crushing process. For this reason, these crusher buckets are ideal for aggregate and demolition applications, where volumes of 35 m³ to 50 m³ per hour are required.
Because material is crushed and re-used on site, the need for machinery dedicated to various processing stages is reduced, transportation costs are minimal and dumpsite fees and double handling is virtually eliminated. These crusher buckets are easily attached to excavators, from 20 t to 36 t, using specially designed mechanical or hydraulic universal quick couplers.
more hpe-africa-crushing&screeningequipment…two An important unit in the McCloskey range is the C38R recirculating cone crusher, with key features that include a metal detector, an anti spin system, integrated hopper and fully hydraulic push button and relief system, with load and material level monitoring. These Telsmith 38SBS cone crushers, which are powered by CAT C9 Tier 3 engines, accept a material feed size up to 200 mm and offer a throughput tonnage up to 220 tph, depending on the closed side setting. The single deck recirculation screen on the same chassis allows oversize material to be returned to the crusher feeder which prevents material oversize wastage and significantly reduces operational costs - there is no double handling and all tasks are handled on one chassis. McCloskey heavy duty track mounted recirculating cone crushers have important safety
features that include a start siren, emergency stops and engine shutdown systems. The screen attachment to the chassis has a bolt-on design for quick screen media change. For effortless maintenance, there is an open chassis design, external belt alignment and visible centralised grease points that provide easy access for routine maintenance. The units have four jacking legs on each corner to stabilise the crusher in uneven terrain. The tracks are bolt on, rather than weld on. The advantage is, in the event of a track problem, the crusher can simply be jacked up and the entire track, including final drive, is removed and transported to the workshop for repair, without any disruption to crushing operations. A key feature of the McCloskey mobile range is the over-ride system which is activated in the event of a sensor failure. more hpe-africa-crushing&screeningequipment‌three Optional features include a roll-in bogie system, hopper extensions, a water pump and dust suppression system and the option of course, medium and fine liners. Wear parts are available locally. These machines are designed to withstand operation in environments with extreme variances in climatic conditions and terrain.
HPE Africa's range of Soosan hydraulic breakers includes the recently launched SU+ series, which has been designed with a higher power to weight ratio and increased impact frequency for greater production efficiency. The newly developed bounce controlled percussion system minimises recoils during hammering work to reduce damage at the hammer and carrier, also improving operator comfort. A thermal stress analysis system controls heat generation and prevents the breaker from excessive heat. As a result, breakers maintain a constant percussion frequency at high temperatures. Greater accumulator capacity ensures a stable hydraulic system, with reduced surges. A valve adjuster allows oil flow to be altered to suit on-site working conditions. A new anti scratch system allows safe operation and durability, even in harsh working conditions and specially developed devices prevent foreign substances flowing into the cylinder. A pressure resistant hydraulic hose reduces vibration and extended tool bushing prevents damage to the piston and cylinder caused by misaligned tool hammering. Applications for these hydraulic breakers include primary and secondary breaking in quarries, site preparation and foundation work, road construction, trenching, tunneling and bench leveling, as well as general construction works.

BLT SA Samson Eco-hoppers for flexibility, efficiency and effective dust control in materials handling Flap'. This divider, which comprises a series of pressed steel sections and vertical rubber flaps, opens to allow the free flow of material into the hopper and closes to prevent the flow of air out of the hopper. When bulk material is released by the grab, it falls through the Flex-Flap and accumulates in the inner hopper below. The hopper system automatically closes as a result of the newly created pressure differential between the hopper and the atmosphere, forming a seal to contain the dust contaminated air. Integral reverse jet filters are positioned around the hopper inlet to extract and clean the dust laden air. Collected dust is then re-cycled into the mainstream of material. The Flex-Flap feature reduces the volume of exhausted air necessary to control fugitive dust and requires the use of small, compact filters rather than a large de-dusting system. blt-samson-eco-hoppers-effective-dust-control …one BLT SA's range of Samson bulk materials handling equipment includes travelling hoppers, which provide efficient handling, flexibility and environmental protection, in the discharge of dry bulk materials.
BLT SA's range of Samson bulk materials handling equipment includes travelling Eco-hoppers, which provide efficient handling, flexibility and environmental protection, in the discharge of dry bulk materials. “Samson Eco-hoppers, which are suitable for discharge by grab cranes, are designed to suit the characteristics and flow properties of virtually any bulk material, including coal, iron ore, gypsum, copper concentrates, soda ash and wood chips,” says Keith Dowie, project development manager for BLT SA's Samson bulk materials handling equipment. “These robust grab unloading hoppers offer handling rates to 5 000 tonnes per hour, depending on grab crane performance.” Eco-hoppers, which are manufactured to withstand tough conditions at ports, also have an effective dust control system that minimises the escape of dust during the grab discharge cycle. Environmental pollution caused by fugitive dust, is a major problem in dry bulk handling. These hoppers have an upper and lower section, separated by a dust retention feature, the 'Flex-

material is to be moved directly off the port to a remote location. For handling difficult materials, like woodchips, one or multiple Samson feeder units can be integrated with the Eco-hopper, to provide controlled rate feeding of virtually any material. Eco-hoppers can be rail mounted or bolted to suitable concrete foundations. For applications requiring a higher level of manoeuvrability, hoppers can be supported on solid rubber filled pneumatic tyres.

LT SA's range of Samson bulk materials handling equipment includes travelling hoppers, which provide efficient handling, flexibility and environmental protection, in the discharge of dry bulk materials. “Samson Eco-hoppers, which are suitable for discharge by grab cranes, are designed to suit the characteristics and flow properties of virtually any bulk material, including coal, iron ore, gypsum, copper concentrates, soda ash and wood chips,” says Keith Dowie, project development manager for BLT SA's Samson bulk materials handling equipment. “These robust grab unloading hoppers offer handling rates to 5 000 tonnes per hour, depending on
These hoppers have an upper and lower section, separated by a dust retention feature, the 'FlexFlap'. This divider, which comprises a series of pressed steel sections and vertical rubber flaps, opens to allow the free flow of material into the hopper and closes to prevent the flow of air out of the hopper.

When bulk material is released by the grab, it falls through the Flex-Flap and accumulates in the inner hopper below. The hopper system automatically closes as a result of the newly created pressure differential between the hopper and the atmosphere, forming a seal to contain the dust contaminated air. Integral reverse jet filters are positioned around the hopper inlet to extract and clean the dust laden air. Collected dust is then recycled into the mainstream of material. The Flex-Flap feature reduces the volume of exhausted air necessary to control fugitive dust and requires the use of small, compact filters rather than a large de-dusting system. The standard Samson Eco-hopper series includes circular hoppers, which are designed to accommodate grab capacities between 1 and 37 m³. Each hopper size has a corresponding high or low level framework, depending on the chosen discharge option. blt-samson-eco-hoppers-effective-dustcontrol…two Custom designed hopper solutions that suit specific application requirements are also available. Discharge of materials from the Eco-hopper may be direct to a belt conveyor for a fixed installation. In this case, the bulk material is reclaimed by a gravity discharge unit which feeds the material onto the conveyor at the required output rate. By using a dust controlled loading spout, the hopper can discharge direct to tipping trucks, where material is to be moved directly off the port to a remote location. For handling difficult materials, like woodchips, one or multiple Samson feeder units can be integrated with the Eco-hopper, to provide controlled rate feeding of virtually any material.

OCSA makes it easier for mines to keep a firm watch on legal compliance
E
mployers could face a court battle when workers believe they have contracted an occupational disease as a result of workplace conditions. The good news is that it is easier than ever to comply with statutory requirements. Mining companies simply need to use the sophisticated occupational health (OH) infrastructure available to them says OCSA, a leading business in workplace occupational health and wellness. Tough conditions Most mining companies - large or small, undertake work that exposes workers to a wide range of hazards. These hazards fall into well-known categories such as physical, chemical, ergonomic, biological, psychosocial and mechanical hazards. “The mining industry needs to keep a firm eye on complying with statutory requirements as well as proactively managing occupational health risks,” says Piet Marais Quality Manager: OCSA Occupational Hygiene and Environmental Services. For instance, asbestos can be mined accidentally, particularly when mining for vermiculite, talc, diamonds and semi-precious stones such as tiger's eye. “Ore should be tested regularly,” says Marais. “This testing should not pose a challenge because there are specialised companies available to support the industry.” OCSA, is a case in point. The organisation has an in-house laboratory designed according to world-class standards to provide a reliable and analytical service with a fast 24-hour turnaround time. In mining, noise, dust, ergonomics, thermal stress, confined spaces, long hours and shift work are common hazards which increase the risk of noise induced hearing loss, respiratory diseases such as pneumoconiosis, musculo-skeletal disorders, heat related disorders and fatigue. Understanding the risk While there is a mandatory obligation to provide a safe and healthy work
24
environment, OCSA cautions that although South African employers contribute to 'insurance', which covers employee accidents and occupational illnesses, many workplaces still function without full compliance and adherence to the rules of the game, leaving them exposed to the risk of court action. Exminers may present for health assessments at the Medical Bureau for Occupational Diseases (MBOD) every 2 years to determine if they have any health effects as a result of exposure to respiratory hazards such as silica dust, asbestos, etc. Employers should use suitably qualified, competent occupational hygiene service providers to implement and manage occupational health programs.
Health and safety culture Unsafe conditions are only a contributing factor in 10% of incidents experienced – it is employee actions or lack of correct actions that contribute to 88% of all incidents. “Health and safety is everyone's responsibility from the CEO to the mining site,” says Marais. OCSA encourages both the employer and employee (particularly the legislated Health and Safety Representatives), to ensure that Health Risk Assessments are carried out and that relevant occupational hygiene monitoring programmes are implemented. A good occupational health management system goes a long way to identifying workers with health problems as early as possible. This creates an opportunity to case manage affected workers timeously and prevent progression to established disease and disablement. Ultimately, this will significantly reduce a company's risk against litigation. OCSA Insight Improving SHE performance Mining companies need to: ŸCommit to identifying hazards through health
risk and hygiene assessments; ŸSensitise and educate workers about health
risks; ŸStart ways to control and eliminate hazards and risks; ŸImplement risk based medical surveillance programmes; ŸEnsure compliance with control measures
including use of personal protective equipment; ŸManage workers with evidence of occupational disease as early as possible in order to limit the extent of disability and suffering; ŸFacilitate the compensation of workers with occupational diseases by submitting claims without delay; ŸImplement information management systems that allow the company to analyse and manage risk e.g. link occupational hygiene data to risk profiles, and risk profiles to job titles. Ÿschedule medical surveillance assessments, track health and absenteeism trends, and keep adequate records of medical surveillance data and hygiene data. Trendsetting partner in workplace health and wellness As a leader in occupational health in Southern Africa, OCSA provides professional health and wellness services to over 500 companies nationally as well as neighbouring countries.

HPE Africa High Power Equipment (HPE) Africa's growth in 2013 can be attributed to its expanded range of equipment, including the new range of Hyundai -9 Series wheel loaders, and its expanding influence in the Eastern Cape says sales manager “The Hyundai -9 series range of wheel loaders includes the HL730-9, HL740-9, HL760-9 and HL780-9. An important feature of the -9 series is the new transmission system. Variable operating modes have been placed into the transmission, ensuring that the vehicles are not fully automatic. The operator has a choice of four driving modes, each suited to different terrains and loads for optimal performance. By having a variable transmission the machines save on fuel,” Sauls explains. The -9 series wheel loaders also come standard with an advanced 5.7 inch eye level display monitor. Sauls observes: “The eye-level display monitor increases operator comfort, as well as safety and accuracy, as the operator never has to look down to read the gauges.” Last year HPE Africa also reintroduced a newer version of the Hyundai R220-7LC,

to use HPE Africa as the sole distributor of the McCloskey product range because of the companies' shared business values.
“The Hyundai R210-7 excavator was introduced earlier in 2013 to compete with cheaper imports, while still providing quality and performance.”
HPE Africa sales and marketing manager Alan Straw highlights that the McCloskey range of products are ideal for the African market. “This is because of its userfriendly and rugged design. They have been designed to be reliable, operatorfriendly and easy to maintain.” Sauls believes HPE Africa's after sales and technical support is a significant value-add to its client base.
HPE Africa is the sole distributor of Hyundai earthmoving equipment in Southern Africa and has been supplying Hyundai earthmoving machines for the past 15 years. The brand however is still relativity unknown in the Eastern Cape region. Earlier this year, HPE Africa opened a second regional branch in Port Elizabeth, following on from the proven success of the Hyundai machines in East London. Another point of growth for HPE Africa during 2013 was its introduction of the McCloskey range of equipment to the local market. McCloskey International is a global leader in the manufacturing of crushing, screening and recycling equipment. The decision was made

DRILLING AND BLASTING Blasting has historically been a risky operation, but AEL Mining Services is intent on paving the way to zero harm and finding the 'missing link' to deliver optimal blasting solutions. This mammoth task requires the collective efforts of the industry to be truly successful, AEL Mining Services is calling on the industry to collaborate on efforts to improve workplace safety and risk exposure in the evolving mining environment.
Z
ero harm is possible, as AEL proved at Kumba Iron Ore's Sishen mine in early 2014, where a record blast of 311 mm holes with a total of 70 8446 t moved was achieved with an excellent safety record of zero injuries and zero incidents. Subsequently, the blasting section managed to set a new record for total tons blasted in a week (7.4 Mt) without an incident. At Sishen, AEL demonstrated its prime, load, tie and/or shoot (PLTS) service, which addresses the requirements of customers that face resource and construction constraints and therefore require a solution to these problems without the need to hire more or upskill existing members of staff. Safety is coupled with convenience due to the combination of AEL's technical expertise and adherence to legal compliance regulations. Leading the way in underground bulk systems “The underground mining method hasn't changed in 100 years,” says Tose. “To make inroads in safety and health, we have fundamentally changed our method. The emulsions we have developed for example can now be mixed where they are needed, even underground. This improves security and controls since the
chemicals only become active when mixed.” AEL's underground bulk system (UBS) comprises three components, emulsions which can be bagged or delivered to the working place through a pipe from surface, a sensitising agent and a pumping mechanism. While widely accepted as the industry standard for underground mining, it is continuously evolving within the walls of AEL's research and development department. New and improved emulsion formulations, pumping systems and value-add services targeted to this industry are constantly being realised as AEL continues in its efforts to improve its offering. Enhancing safety and reducing risk is one of the major drivers behind AEL Mining Services, and the company is constantly striving towards creating innovative technological advancements in the mining industry that better promote safety in the workplace and aim to reduce the exposure to risk. “This is about using the technology we have to improve on safety. There is a big push as an industry to make it safe and getting rid of the 'explosive' part makes it safer,” says Tose. “Here we have the solution – the missing link – now it is about getting it into the marketplace.” As an added benefit, UBS technology “is only explosive when mixed, so this prevents theft,” says Tose. Pilferage of explosives has been a challenge for many mines, but the UBS in-line
mixer and gassing solution is controlled on surface and the product only becomes an explosive once it is mixed through the lance at the stope face underground. Ever improving in Africa and beyond Improving the delivery of emulsions underground is an ongoing concern for AEL, as is “how we get even deeper,” says Tose, but the company's vision for ongoing improvement does not end with its products. AEL is not a product peddler but rather a value-adding service provider that strives to optimise its customers' mining operations. “For us, it is about being connected to a certain service, and we are interested in developing and matching solutions to problems. We want to get involved in the end solution rather than just the product itself,” says Tose. Another concern for AEL in terms of improving in Africa “is developing the mining industry while conserving national interest,” says Tose. “It is important to bring local communities on board. There is a lot of potential in Africa and the national interest is large, but it needs to be balanced.” Tose provides the new generation Bengalon nitrate plant in Indonesia as an example. “Our kits are mobile, so we can put plants in.
