Murray & Roberts Cementation continues to add to its order book of business in southern Africa, with the company saying it is engaged in a number of projects in South Africa and having project prospects in nearby countries.

According to Graham Chamberlain, New Business Director at Murray & Roberts Cementation, the busy pipeline of projects demonstrates the mining sector’s faith in the company’s industry knowledge and depth of skills. In southern Africa, the main projects underway are at De Beers’ Venetia Mine, Ivanhoe Mines’ Platreef project and Palabora Mining Company.

At the Venetia Underground project near Musina, work has been ongoing since 2013 in one of the largest investments in South Africa’s diamond industry in decades. Transitioning from open-pit to underground mining will extend the mine’s life until 2046. Murray & Roberts Cementation has been engaged in sinking, lining and equipping of two shafts – the production and service shafts – to a depth of 1,080 m. The company also developed a decline tunnel and is completing associated surface and underground infrastructure, in a project whose scope included raiseboring work to establish ventilation infrastructure.

“In this maturing project, the mine is now getting into ore and starting to develop the infrastructure levels,” Chamberlain says. “At the shaft bottom, good progress continues to be made with the construction of workshops, pumping stations, silos and loading arrangements.”

Murray & Roberts Cementation is also conducting all the infrastructure development at Ivanhoe Mines’ Platreef project near Mokopane. This includes the sinking of a 5.1 m ventilation shaft to meet horizontal development at 950 m below surface. To achieve the high accuracy levels demanded by the project, the raiseboring equipment was guided by directional drilling technology.

“A unique aspect of this project is that the shaft will be hoisting ore at that same time as allowing upcast air to reach surface,” Chamberlain says.

Another vent shaft by Murray & Roberts Cementation – measuring 8.5 m in diameter and reaching a depth of 1,200 m – is nearing completion at Palabora Mining Company near Phalaborwa. Part of the mine’s Lift II expansion, the project has earned an impressive safety record – being fatality free and achieving 574 days without a Lost Time Injury since 2022. Ground conditions were among the reasons why a blind sink was chosen as the optimal method instead of raiseboring, as the side walls needed immediate support to prevent scaling.

“We also have a number of services projects underway related to raiseboring, grout plants and rehabilitation,” Chamberlain explains. “Much of our work in this field is focused on old infrastructure that requires maintenance, repairs or upgrades; we also conduct extensive vertical work in ore passes and silos.”

The company carries out vital rehabilitation in ore passes where ground conditions have deteriorated to prevent ore from moving smoothly – thereby risking production targets. Innovating safer techniques for this work, Murray & Roberts Cementation has developed the tube-and-fill method, first applied about seven years ago at an underground platinum mine in South Africa. These installations are also expected to outlast the lifespan of an ore pass rehabilitated with traditional shotcrete.

“On the engineering front, we continue conducting rebuilds of underground mining equipment at our Bentley Park facility near Carletonville,” Chamberlain says.

He highlights the work of the company’s design department, which remains extremely busy with feasibility studies associated with vertical work. With the renewed interest in commodity segments like copper, there is also previous work that customers are asking Murray & Roberts Cementation to review and update.

Training in underground mining and related skills at the company’s Training Academy on Carletonville continues to empower many thousands of learners each year, Chamberlain points out. This skills development is done on behalf of clients, as well as for the company’s own requirements.

“At any one time, we can host about 420 learners, and we are generally at full capacity,” he says. “We have just recently upgraded these facilities to further enhance training technologies that allows learning to take place safely but in a realistic environment.”

In compliance with many African countries’ localisation regulations, Murray & Roberts Cementation has registered companies in eight countries in the Southern African Development Community – most of which have seen the company active with raiseboring. Chamberlain notes that there are specific opportunities in Zambia that the company hopes to capitalise upon in the near future, and is encouraged by the mining sector’s progress in countries like Namibia and Botswana.

The Kamoa-Kakula copper complex, a joint venture between Ivanhoe Mines, Zijin Mining Group and the government of the Democratic Republic of the Congo (DRC), has partnered with Elessent Clean Technologies to install a new 2,500 t/d smelter off-gas MECS® sulphuric acid plant.

In conjunction with global EPC partner, China Nerin Engineering Co. Ltd, the new acid plant will be part of a new 500,000 t/y direct-to-blister flash copper smelter that is under construction at Kamoa-Kakula, as part of its Phase 3 expansion. Upon completion of the Phase 3 expansion, Kamoa-Kakula is projected to be the fourth largest copper operation globally.

The MECS sulphuric acid process incorporates state-of-the-art technologies, such as the MECS pre-conversion technology and the MECS DynaWave® gas cleaning technology. DynaWave scrubbers, the gold standard in gas cleaning applications, according to Elessent, clean and condition the upstream off gas of the smelting furnace at the sulphuric acid plant. The MECS pre-conversion technology is a novel approach for processing off-gas streams with elevated sulphur dioxide concentrations while consuming significantly less power, according to the company.

The MECS sulphuric acid technology has been in use for nearly a century in the phosphate fertiliser, non-ferrous metals (leaching & smelting), oil refining and general chemical industries. MECS technologies feature breakthrough solutions, many of which have revolutionised the performance, quality and cost-effectiveness of customer operations, according to Elessent. They include MECS heat recovery systems (HRS™), MECS SolvR® regenerative SO2 scrubbing and MECS MAX3™ sulphuric acid production technology. Integrated into these MECS technologies are specialty products such as catalysts, Brink® mist eliminators, DynaWave scrubbers, ZeCor® corrosion resistant alloy products and acid coolers, all of which are specifically designed for the most demanding operating environments. The MECS technology has more than 1,000 sulphuric acid plant licenses and projects.

David Mitchell, Kamoa-Kakula’s Senior Project Manager for the smelter project, said: “At Kamoa-Kakula we aim to set a new industry standard by being the greenest major copper mine in the world. It helps that DRC not only has an incredible mineral endowment, but also has an abundance of clean hydroelectricity to power its mining industry. However, we also need the right technology to extract the copper in a sustainable way. By using the MECS acid plant design and its incorporated technologies, our new plant helps achieve our path to net zero.”

Eli Ben-Shoshan, CEO, Elessent Clean Technologies, said: “Kamoa-Kakula is one of the world’s fastest-growing major copper operations. Partnering with NERIN on the mine’s greenfield smelter complex is very exciting. It is a great honour to work with the owners of what is anticipated to be one of the greenest major copper operations on the planet.”

The Kamoa-Kakula copper complex has been in commercial operations since July 2021. The operation is currently undergoing its Phase 3 expansion, which will increase copper production to over 600,000 t/y copper from the September quarter of 2024.

Platreef-Ivanhoe-Murray&Roberts

Murray & Roberts Cementation to accelerate ore hoisting at Ivanhoe Mines’ Platreef project

In a project innovation that will allow early hoisting of ore at Ivanhoe Mines’ Platreef project, in South Africa, Murray & Roberts Cementation will be repurposing its 3 Shaft – a ventilation shaft – to serve a dual function.

“This is a unique project in many respects, as the shaft will be hoisting ore at that same time as allowing upcast air to reach surface,” Graham Chamberlain, New Business Director at Murray & Roberts Cementation, says. “We were able to bring our well experienced experts into the planning process to develop a safe and effective solution.”

The project has followed the sinking of the vent shaft by Murray & Roberts Cementation, which had required very accurate drilling, using raiseboring equipment guided by directional drilling technology. The 5.1-m diameter shaft meets horizontal development at a depth of 950 m below surface.

“During this process, Ivanhoe looked at bringing forward some of their ore generation activities, and this required adding hoisting capacity,” Chamberlain explains. “The timeline for their main shaft meant that it would not be able to contribute to this capacity, so a team was established to consider how to retrofit the vent shaft into an early hoisting shaft.”

As an integral part of that multidisciplinary team, Murray & Roberts Cementation conducted a feasibility study on the options, allowing for the selection of the most suitable methodology. The company also carried out the necessary designs, including winders and headgear as well as hoisting and tipping arrangements. In September 2023, the project was awarded to Murray & Roberts Cementation to implement, and is scheduled to take about two years.

“This project stands out in terms of innovation, adaptability, teamwork and design,” Chamberlain says. “With our many decades in the sector, we were able to draw on hundreds of years of experience in mining – and leverage this in our design team.”

Among the range of technical challenges is the need to work within the vent shaft while it is performing its function of channelling an upcast current of air to surface. Any blockage of the air current in the shaft would affect the development operation of the mine, so this is critical to avoid.

“There needs to be periods during which we can reduce the ventilation, but we will have to ensure that air flow is always adequate,” Chamberlain says. Another vent shaft is planned to add ventilation capacity for the future.

Chamberlain points out that it will be necessary to deal with the slight deviations in the shaft; while accurately drilled, vent shafts are not designed to the same tolerances as hoist shafts. An important aspect of the design was the steelwork required to accommodate those deviations.

“The work will be conducted by a relatively small team of our highly skilled people,” he says. “This will include the installation of a compact headgear using refurbished winders from our strategic stockholding.”

The infrastructure will employ technology that will allow man-less operation to enhance safety, using automated processes in loading and measuring functions, for instance. The project will require specialised subcontractors on much of the equipment employed, but the more day-to-day consumables are procured locally to support local businesses.

“In the absence of a supplier, we would then develop their capability through our procurement system and enterprise development commitment,” Chamberlain says. “In this way, we foster small businesses and help to nurture them until they are self-sustaining.”

Satellite-enabled IoT can be mining industry game changer, Viasat says

As the mining industry faces mounting pressure to enhance its sustainability efforts, a significant majority (86%) of mining leaders have expressed intent to bolster their Internet of Things (IoT) adoption, according to Viasat’s Nicholas Prevost*.

This may point to growing acceptance in the industry that connectivity can help meet operational demands and demonstrate tangible sustainability progress to customers, investors and the general public in the coming year.

The capabilities of IoT – such as remote monitoring and control – are extensive for mining firms. The technology can support a variety of needs, whether it be through connected machinery that collects and analyses data, or through weather analysis to predict and mitigate against extreme weather.

To recognise IoT’s value and increase its use, it is vital for mining firms to first understand how the technology can enhance its mission-critical operations. Overall, IoT can help companies improve workforce safety, operational efficiency and offer cost-savings; as well as reduce environmental impact of their operations. All of which can lead to safer and more sustainable mining operations.

Safeguarding workforce and assets

According to the European Commission, mining and quarrying had the highest count for fatal accidents at work in the EU in 2020. By its very nature, the mining industry can be dangerous if operations and staff are not closely monitored and protected in near real time.

IoT-enabled capabilities, such as remote dam monitoring and pump control, can help mining companies reduce the need for personnel on the ground. This in turn, supports efforts in minimising accident rates and helping to prevent fatalities as the number of staff operating in challenging environments is reduced.

More widely, through solutions like weather monitoring, companies can also help protect their staff and assets from extreme events, like storm or lightning strikes. This also reduces accidents that can be associated with being in remote, unsheltered locations.

Additionally, capabilities like remote vehicle tracking can help mining operators keep a closer eye on personnel. An example of this is Viasat’s partner, Ivanhoe Mines, that has integrated satellite-connected telemetry solutions to track assets and improve driver safety. In doing so, operators can closely monitor the speed at which their staff are travelling between locations and reduce the risk of accidents occurring. Through location monitoring, it can also establish if a vehicle hasn’t moved for a period of time and the driver can be contacted as a precautionary measure or if an issue occurs.

Enhancing operational efficiency and cost-savings

IoT also holds significant potential in improving everyday efficiencies for mining firms. For example, closed mine sites, which are either abandoned or in ‘care and maintenance,’ require careful monitoring. Although sites may not be in operation, companies are still responsible for compliance with environmental regulations, health and safety and security. Companies must send staff out to check in on these sites – which can be costly and potentially dangerous due to legacy infrastructure, hostile climates and remote environments.

Monitoring of these mines can be supported through IoT sensors automatically, remotely and in real time: reducing the need for personnel to be physically present. Solutions can include air monitoring or on-demand HD video and access control, all of which can provide peace of mind for managers, reduce costs, improve visibility and allow monitoring of the biggest risks including flooding events and waste management.

Monitoring for ESG

With growing pressure on all industries to improve their sustainability initiatives and take clear action towards net zero goals, ESG has become a main concern in mining. Considering this, investing in IoT solutions can provide a noticeable return for mining companies who are looking to not only improve the sustainability of operations. Examples include areas like water management and tailings storage to avoid leaks and failures that can impact operations, communities and the environment – and streamline ESG reporting.

Through real-time monitoring and alerting, IoT solutions can help to capture and analyse data from sensors on sites and feed into automated reporting solutions on user-friendly platforms. These capabilities allow mining specialists to make more informed and quicker decisions in relation to water usage or failures and help mitigate the considerable impact on operations.

Real-time updates can also improve transparency in reporting, which is paramount for mining companies to maintain the trust of their investors and to be seen to be compliant with industry standards. By connecting the operations of the mining sites, firms can more easily track compliance with ESG regulations and reduce the risk of fines or legal action. That ensures a degree of transparency that can improve relationships with stakeholders.

Leverage satellite connectivity

Due to the typically remote locations of mining sites, conventional terrestrial connectivity is often unavailable or unreliable. With its global reach and reliability, satellite connectivity offers a vital alternative as well as a resilient back-up to terrestrial networks, regardless of a mine’s geographic location.

Satellite-enabled IoT solutions are being used in many cases within mines around the world. Viasat says it plays a pivotal role in ensuring these solutions are supported.

Leveraging Viasat’s L-band network – a global satellite network for IoT solutions – mining firms can benefit from high network availability of up to 99.9% through a globally standardised satellite connectivity solution, according to the company. Increased availability is also particularly relevant for short-term contractors or mining companies operating in regions that are remote and seismically unstable. In both cases they may not be willing to invest in costly, fixed communications infrastructure.

Overall, considering its benefits across operational efficiency and sustainability, the adoption of satellite-enabled IoT has the potential to be a game-changer for mining firms looking to future-proof their operations amid changing business environments.

Zest WEG to supply Ivanhoe Mines with range of electrical, energy solutions for Kipushi

Base metals, Comminution of minerals, Mineral project development, Mining consumables, Mining equipment, Mining services, , , , , , , , , , ,

As part of Ivanhoe Mines’ refurbishment of the historic Kipushi zinc-copper mine in the Democratic Republic of Congo (DRC), Zest WEG is to supply a range of electrical and energy solutions.

Ivanhoe Mines acquired its 68% interest in the Kipushi project in November 2011; the balance of 32% is held by the DRC’s state-owned mining company, Gécamines.

According to Luveshen Naidoo, Business Development External Sales Engineer for Mining and Industrial at Zest WEG, this includes a 14 MW power plant, motor control centres (MCCs), WEG medium voltage (MV) variable speed drives (VSDs) and a WEG 1,200 kW MV motor for the mine’s ball mill. The company is also the preferred supplier of low voltage (LV) motors, and will supply these to a range of mechanical OEMs servicing the mine. Delivery of the equipment is expected to begin in the September quarter of 2023.

“Our diesel powered plant, which will provide the mine with backup energy, has been designed to comprise 12 generator sets – each rated at 1,587 kVA and 400 V,” Naidoo says. “Assembled at Zest WEG’s specialised Cape Town facility, the plant includes MV switchgear, six 3150 kVA ONAN type 400V / 6.6 kV step-up transformers, a 40,000 litre fuel tank and an automated fuel system.”

He highlights that splitting the plant design into smaller generating units ensured engines and alternators were readily available, securing a quicker delivery time. The configuration of the plant in this way also gives the mine greater energy security in the case of maintenance or breakdown. The gensets can also be transported to site using conventional trucking, without the need for abnormal load vehicles.

The MCCs are being supplied for use in an established substation on the Kipushi zinc-copper mine, as well as for a containerised substation elsewhere on the site. To accommodate space constraints, the MCCs are designed for a back-to-back configuration with a compact bucket size, Naidoo explains.

“This ensures that the equipment will fit in the available space while still meeting the client’s specification and stringent IEC standards,” he says.

For the mine’s SAG mill, Zest WEG is providing the WEG W60 MV motor rated at 1,200kW – a unit for the demanding applications and aggressive environments found in the mining sector, Naidoo says. The reduced motor weight holds distinct benefits, he notes, including a compact base plate or plinth onto which it is mounted – and lower installation costs. The motor’s IP55 rating ensures the motor is well protected from dust or water ingress.

To meet the client’s needs for the MV VSD to drive the ball mill motor, WEG’s MVW3000 unit is being supplied – a compact design with an integral dry-type transformer. To facilitate the dissipation of heat, Zest WEG designed a ducting system for this 1,200 kW VSD which will reduce the need for cooling of the substation.

As the client’s preferred brand of LV motors, the WEG W22 motor is being made available to Kipushi’s mechanical supply OEMs. Among the key benefits of this WEG IE3 motor is its energy efficiency, Naidoo says. This preferred brand strategy makes it more cost effective for the mine to keep the necessary consignments of spares for maintenance and servicing.

In putting together its proposals for the client, Zest WEG worked closely with the engineering consultant METC Engineering in the detailed design stage.

First-line support for Zest WEG’s equipment will come from Panaco, the company’s Value Added Reseller in the DRC.

More SEW-EURODRIVE X.e-series power packs on their way to Kamoa-Kakula

Base metals, Mine operation news, Mining consumables, Mining equipment, Mining services, Power supply for mines, Uncategorised, , , , , , , , , ,

With well over 100 units already delivered, SEW-EURODRIVE in South Africa is set to continue supplying Ivanhoe Mines’ Kamoa-Kakula copper complex in the Democratic Republic of Congo, a joint venture with Zijin Mining of China, with a wide range of its X.e-series power packs, the company says.

According to Willem Strydom, Business Development at SEW-EURODRIVE, the power packs – which are integrated units comprising gearbox, coupling and motor – will be part of Kamoa-Kakula’s Phase 3 expansion. Since the mine’s first phase of development over five years ago, SEW-EURODRIVE has worked closely with both Ivanhoe and the engineering, procurement and construction contractor.

“As in previous phases of the mine’s development, our robust high quality power packs will provide reliable solutions in on-site applications such as conveyors, agitators and slurry pumps,” Strydom says. “The size range in the order makes use of our wide capability range to provide a total solution, ranging from 55 kW units to 500 kW units.”

The latest order includes several X.e series power packs for conveyor applications, planetary gearboxes for feeder applications and spare gearboxes. The equipment will be delivered in staggered shipments this year. While the mine typically undertakes the installation of the equipment, SEW-EURODRIVE sends technical teams to site to check final alignment and overall installation parameters.

The company has expanded its after-sales service teams considerably in recent years, allowing it to support the growing base of equipment throughout Africa. Its projects and engineering teams have also grown – developing a depth of experience to assist customers right from design phase onwards.

Strydom notes that SEW-EURODRIVE has significantly developed its infrastructural foundation in South Africa, and plans to develop a physical representation in over 23 other African countries. As a priority country for the company’s strategy, there is expected to be a representative in place in the DRC in 2023, he explains. Field service teams from South Africa are frequently at Kamoa-Kakula to assist with servicing of the existing power packs operating on the site.

“Our local assembly capability in our new facility in Johannesburg – combined with our ability to source from the group’s other global operations – has allowed us to meet the tight delivery deadlines for this substantial order of equipment,” he says. “Our global footprint and production capacity mean that we can deliver faster than most players in our field, and this is often an important factor for our market.”

While the company previously imported the larger X.e Industrial gearboxes from Germany, it is now able to assemble these in the new South African facilities. As part of its service, SEW-EURODRIVE will also handle the logistics of getting this large volume of equipment to site. The company’s training centre – the Drive Academy – in Johannesburg has also made a valuable contribution by providing training on the equipment and its maintenance, it says.

In this project, the tropical climate was another important factor in the customer’s design requirements. This required the inclusion of certain cooling and paint specifications in the contract.

SEW-EURODRIVE Head of Engineering, Andreas Meid, explains that special breathers were part of the design in response to high humidity levels – and served to ensure no moisture in the gearboxes. In outdoor applications where sun exposure was high, covers were also included to reduce heat build-up. Cooling fans were also optimised in certain cases to ensure optimal performance.

He highlights that Kamoa-Kakula is one of many projects in Africa to request the installation of monitoring equipment on the power packs. This facilitates real-time monitoring, using specialised sensors to measure key indicators like vibration and temperature from anywhere in the world.

“This allows the operation to monitor the equipment remotely, receiving early warnings of any issues in performance,” Meid says. “Responding timeously to this information can prevent serious damage and avoid unplanned downtime.”

As a preferred supplier, SEW-EURODRIVE first delivered a multitude of X.e Series power packs between 2019 and 2021 for the mine’s initial development phase.

For Kamoa-Kakula’s Phase 2 expansion, which doubled the concentrator plant capacity, SEW-EURODRIVE supplied many standard X.e series power packs for the conveyors as well as planetary gearboxes for the feeders.

Murray & Roberts Cementation hits the accuracy mark on Platreef ventilation shaft development

Murray & Roberts Cementation is helping Ivanplats deliver the Platreef project in South Africa through the provision of drilling services at the ventilation shaft.

The dual purpose use of the new ventilation shaft at Ivanplats’ Platreef project required extreme pilot hole accuracy, according to Murray & Roberts Cementation.

The vent shaft, or Shaft 3, which meets horizontal development at a depth of 950 m, also needs to be equipped with a hoist and rope guides to carry personnel in the case of emergency. The rope guides for the hoist require the shaft to be drilled vertically within tight parameters. According to Dirk Visser, Senior Project Manager at Murray & Roberts Cementation, this meant offering the client minimal deflection of the pilot hole using a continuous steering tool.

“Using the well-proven German-designed-and-manufactured Micon, Rotary Vertical Drilling System (RVDS), we were able to achieve the set parameters required for a rope guide installation,” Visser says. “The worst deflection was no more than 0.05% – or 452 mm – and, by the time we bottomed out, the deviation was only 0.02% or 226 mm off centre over a final drilling depth of 950 m.”

Micon’s specialised RVDS is a continuous self-steering tool working on a close loop system which steers the tool using two-axis gyro inclination sensors that activate the hydraulic steering system. It can determine in real time if there is any deviation from the vertical course, and communicate this information to the operator on surface via pressure waves in the drilling water by converting the pressure waves into information through transducers, according to the company.

The Murray & Roberts Cementation drilling team not only ensured accurate directional results, but also optimised the performance of the RVDS. By keeping an eye on key variables like voltage levels and water cleanliness.

Visser highlights that drilling to these tolerances with this highly technical equipment demands a very experienced team. On this project, for instance, the most ‘junior’ person has worked with the RVDS for 15 years, while another member has 28 years of experience in raiseboring.

Platreef is owne 64% by Ivanhoe Mines. A 26% interest is held by Ivanplats’ historically disadvantaged, broad-based, black economic empowerment (B-BBEE) partners, while a Japanese consortium of ITOCHU Corporation, Japan Oil, Gas and Metals National Corporation, and Japan Gas Corporation, owns a 10% interest in Ivanplats.

In May, Ivanhoe Mines said that underground development work had been focused on the vertical development of waste passes between the 750-m, 850-m and 950-m levels, and lateral development towards the orebody, as well as lateral development required for underground infrastructure on each level including access to the bottom of Shaft 3 on the 950-m level. Shaft 3, with a diameter of 5.1 m, is currently being reamed with approximately 150 m of 950 m completed to date, it said. Planned completion was scheduled for the December quarter of 2023.

Platreef’s commercial production is expected in 2024, with Shaft 2 now expected to be commissioned in 2027. The initial scope of the phased development plan is to fast-track Platreef into production, starting with an initial 700,000-t/y underground mine using the existing Shaft 1 and a new on-site concentrator. Platfreef, Ivanhoe says, is projected to be Africa’s lowest-cost producer of platinum-group metals, nickel, copper and gold.

Epiroc says it has won a large order from JCHX Mining and Construction Ltd for equipment to be used at the Kipushi underground project in the Democratic Republic of the Congo.

Kipushi is an underground mine that is reopening under the leadership of Kipushi Corporation, a joint venture between Ivanhoe Mines of Canada and Gécamines, a DRC state-owned mining company.

JCHX, a mining contractor, has ordered several Epiroc loaders, mine trucks and drill rigs, including service support, for use at the zinc, copper, germanium and silver mine in the Haut-Katanga, province in southern DRC. After decades of production, the mine closed for care and maintenance in 1994. Construction started last year to re-open the mine, with late 2024 as target to start production. The mine will be powered by clean, renewable hydro-generated electricity, according to the owners.

The equipment order is valued at about $17 milion and was booked in the March quarter of 2023.

“We look forward to supporting JCHX in making operations at the Kipushi mine as safe and productive as possible,” Helena Hedblom, Epiroc’s President and CEO, says.

Sami Niiranen, President of Epiroc’s Underground division, said: “JCHX has been a customer of Epiroc for many years, both in Africa and Europe, and we are pleased to continue delivering innovative solutions that will help to optimise operations at Kipushi.”

JCHX International Division President, Youcheng Wang, added: “From the group headquarters to the front-line team, Epiroc sets the highest priority on this equipment order, also when it comes to on-site technical support.”

The ordered equipment, manufactured in Sweden, includes Scooptram ST14 loaders, Minetruck MT42 haul trucks, and Simba production drill rigs. The Scooptram and Minetruck machines will be equipped with Epiroc’s telematics system Certiq, which allows for intelligent monitoring of machine performance and productivity in real time, and with Epiroc’s Rig Control System, RCS, which makes them ready for automation and remote control.

Delivery begins shortly and will continue into early 2024.

Kamoa Copper SA has selected Metso Outotec to supply a high-capacity direct blister furnace to the company’s copper mining complex expansion project in the Democratic Republic of Congo.

The value of this type of a delivery is typically between €30-40 million ($30-40 million).

Metso Outotec’s scope of delivery consists of key equipment and automation for the direct blister furnace designed for the production of blister copper in a single flash furnace without the need for separate converting stages. The 500,000 t/y copper throughput furnace will have the largest licensed flash smelting capacity in the world, according to Metso Outotec.

The scope also includes intelligent safety and monitoring automation systems for the furnace.

Jyrki Makkonen, Vice President, Smelting at Metso Outotec, said: “Non-ferrous metals play a key role in the green transition, and a major increase in global copper production is required to support this transition. We are pleased to support Kamoa Copper in their ambitious expansion project, in which high capacity and reliable, sustainable processes play a vital role. Our collaboration has been excellent throughout the initial stages of the process, including the initial study work, basic engineering as well as pilot testing.”

Metso Outotec has delivered more than 60 flash furnaces around the world since the 1950s, with the technology being the most used in pyrometallurgical copper production. The Metso Outotec Flash Smelting Process is, the company says, the cleanest smelting method available and part of the company’s Planet Positive offering.

Last month in its quarterly report, Ivanhoe Mines, which has a 39.6% interest in Kamoa-Kakula, said a new 500,000 t/y direct-to-blister flash smelter was to be constructed as part of the Phase 3 expansion at the mine.

Upon commencement of Phase 3 production, the Kamoa-Kakula Mining Complex will have a processing capacity in excess of 14 Mt/y, with increased copper production capacity of approximately 600,000 t/y. This production rate will position the Kamoa-Kakula Mining Complex as the third-largest copper mining operation in the world, according to Ivanhoe.

Commissioning is expected in the December quarter of 2024.
