SGS tackles critical mineral testing, pathfinder analysis with new automated pXRF solution

SGS, a leading testing, inspection and certification company, has unveiled Automated pXRF (Portable X-ray Fluorescence) technology to, it says, further support its clients in unlocking future-focused solutions.

Designed and developed by SGS and Evident, this solution marks a significant leap forward from the conventional, manual XRF process or the in-field pXRF service, SGS claims.

The current method of manual XRF analysis requires dedicated operators to load and unload each powder rock sample individually. SGS’s Automated pXRF technology introduces a mechanised solution that streamlines the entire process. This innovation provides a more stable and reliable environment and allows operators to load up to 20 sample trays, improving efficiency of the analysis, according to the company. The new design and capability reduces turnaround time and analysis costs, expediting the delivery of critical insights for geological modelling.

The Automated pXRF system also increases the quality and consistency of sample measurement with high accuracy and repeatability, while reducing human error associated with manual loading and operator involvement during analysis. This advancement improves data reliability and enhances decision making for businesses reliant on precise analysis across critical mineral analysis and gold and lithium pathfinders.

Juan Smith, General Manager of Natural Resources Australia, and Regional Geochem Manager for Southeast Asia Pacific, said: “Our clients are constantly looking at which technologies can deliver better and faster results, and automated pXRF will be a game changer. This innovation aligns seamlessly with our dedication to providing industry-leading solutions that redefine standards. The Automated pXRF system reflects SGS’s unwavering commitment to efficiency, accuracy and safety, ultimately benefiting our clients and the environment.”

SGS said the unveiling of SGS’s Automated pXRF technology is poised to “reshape” critical mineral and pathfinder analysis, setting new benchmarks for efficiency, quality and safety.

SGS in Australia is already providing the service to several Tier One mining companies, ensuring bespoke solutions for each client, it says.

The company concluded: “With its capability to process a high volume of samples while reducing costs and enhancing data reliability, SGS continues to lead the way in technological advancements within the TIC industry.”

BHP to receive ‘world’s first carbon neutral conveyor belts’ from China’s Wuxi Boton

China’s Wuxi Boton has announced the world’s first carbon neutral conveyor belts for delivery to BHP’s Spence copper mine in Chile in August as part of an exclusive pilot project between the two companies.

The two companies jointly developed this pilot project, under which the conveyor belts were verified by SGS, a leading testing, inspection and certification company, as meeting the requirements of PAS 2060:2014 (specification for the demonstration of carbon neutrality).

SGS awarded the world’s first certificate of “Achievement of Carbon Neutrality for Steel Cord Rubber Conveyor Belt” to a batch of belts produced by Boton for BHP. The conveyor belts will be shipped to BHP’s Spence copper mine, where they will be used in the production and transportation of Spence mining products to customers around the world, including China.

The scope of the pilot project was for Wuxi Boton, as the incumbent contractor for BHP’s operations at both Minerals Australia and Minerals America, to select the conveyor belts to be ordered by BHP and identify how to offset the estimated greenhouse gas (GHG) emissions associated with the production of those conveyor belts using high-quality carbon offsets prior to delivery.

BHP’s Group Procurement Officer, James Agar, said: “Wuxi Boton have been a reliable partner to BHP for over eight years, supplying high-quality conveyor belts to our assets in Australia and Chile. Both companies are committed to mitigating climate change in accordance with their respective climate targets and goals. This shared vision of a better world led Wuxi Boton, in December 2021, to extend the offer of an exclusive pilot to deliver a carbon neutral conveyor belt to BHP.

“The partnership with Wuxi Boton has been invaluable in helping BHP verify the feasibility of using high-quality carbon offsets to GHG emissions in our supply chain (Scope 3) and grow the potential demand for supplying ‘traced’, ‘low carbon’, or ‘carbon neutral’ products amongst our suppliers.”

Wuxi Boton’s Chairman, Zhifang Bao, said: “It is difficult for any enterprise to achieve low-carbon transformation on its own. Only by building a global platform, co-operating with the whole industry chain, and jointly exploring low-carbon technologies and road maps can we reach the other shore.

“Therefore, joint innovation is an inevitable choice. Instead of passively accepting, it is better to take the initiative to lead, which is a very important choice faced by enterprises all over the world. We are pleased to see that the partnership between BHP and Boton has expanded from a single business level to a strategic synergy level. In the journey of global energy transition, leading companies, including Boton and BHP, are jointly working towards building a more sustainable future.”

Strategically located in central Ivory Coast, the Yamoussoukro laboratory is close to key mining exploration sites. SGS employees are on hand seven days a week, supporting discoveries for greenfield as well as brownfield projects by providing full fire assay analyses with quick turnaround times, the company said.

Aurelien Nguessan, Laboratory Manager, said: “SGS can now offer mining exploration companies in Ivory Coast complete support, going above and beyond our existing sample preparation capabilities. It’s an exciting time for the industry – and for the country as a whole.”

This new laboratory will complement the services already offered by SGS’ commercial geochemistry labs in the region, including those in Tarkwa (Ghana), Bamako (Mali) and Ouagadougou (Burkina Faso).

Nussir to present zero-emission mining plan at The Electric Mine

Nussir ASA and its ambition to develop the world’s first zero-emission copper mine in Kvalsund, Norway, will end up becoming a case study the whole mining sector learns from.

While some pioneering mining projects are aiming for all-electric operations through the use of battery-electric equipment, Nussir argues its copper project would be the first truly all-electric zero emissions mine in the world as all machines and processes will be powered by renewable energy.

With a brand new (as of January 31, 2022) all-electric feasibility study from SRK in hand, the company is able to outline a project that would involve the development of an underground mine extracting ore from the Nussir and Ulveryggen orebodies. These two have reserves of 162,000 t of contained copper, according to a recent report from the consultants. Total resources, including the inferred resource category, stand at about 80 Mt of ore, according to the company.

SRK is not the only company helping Nussir achieve its vision. It has signed up Leonard Nilsen og Sonner AS (LNS) to carry out potentially the largest mining contract in Norwegian history with 130 km of tunnelling over 10 years; as well as worked with leading OEMs on all-electric mobile equipment; Woodgrove on flotation, instrumentation, automation, flowsheet, PID and process design; Metso Outotec on milling; SGS on flotation, grinding and settling test work; Sintef on rock mechanics; and SRK on the mine plan itself, scheduling and capital and operating expenditure calculations.

Øystein Rushfeldt, CEO of Nussir

The company has also managed to obtain all necessary permits to start construction of the mine, which is located on the site of a former operating open-pit that ceased operations in 1979; and, importantly, signed a Cooperation Agreement with the Hammerfest Municipality as a way of indicating broad support from local political parties.

With the publication of feasibility study and news of further contracts and financing due in the first half of this year, the news flow and attention is due to ramp up in 2022.

Attendees of The Electric Mine 2022, in Stockholm, Sweden, on February 17-18, can hear all about this from Øystein Rushfeldt, CEO of Nussir, in his presentation ‘Nussir: The path to zero-emission mining’.

Evaluate ore sorting options at prefeasibility study stage, TOMRA’s Rutledge says

TOMRA Mining is making a case for its sensor-based ore sorting solutions to be evaluated earlier in the mining project evaluation phase, with Jordan Rutledge, Area Sales Manager, arguing that consideration of its use at the very beginning of flowsheet discussions can influence up- and down-stream equipment selection.

The company’s sensor-based ore sorting systems have spread across the mining sector, migrating from industrial minerals and diamond operations to base and precious metals.

Speaking at a sensor-based sorting seminar in Toronto, Canada, held late last month, Rutledge (pictured) said the use of the technology needed to be considered early in the mine development scope in order to leverage the most benefit for the operation.

“Sensor-based sorting should be considered in the flowsheet from the beginning and evaluated in prefeasibility studies to see if it is suitable for the project and will add value to the plant,” she said.

“In many cases, sorting works really well and, as we continue to go towards a green economy, the use of our resources is vitally important. In order to make the best use of them, sorting plays a critical role.”

Rutledge, an event organiser and presenter, joined 40 participants from across Canada at the seminar, which included representatives from miners such as Agnico Eagle, Capstone Mining and Cheetah Resources; from laboratories such as testing and certification company SGS and the Saskatchewan Research Council ; from engineering companies such as DRA Global, Primero, CIMA and Halyard; and students from the University of Toronto.

“The event highlighted the important role of sensor-based sorting technologies in green mining and their potential to unlock significant value in mining projects, as well as the possibilities of digitalisation for supporting customers and managing connected equipment,” TOMRA said.

SGS adds Chrysos PhotonAssay services to Australian Minerals Regional Hub

SGS says it is expanding its service delivery in obtaining Chrysos PhotonAssay™ technology as an alternative to traditional fire assay procedures.

The two companies – SGS and Chrysos – have reached an agreement to install a PhotonAssay unit at SGS’s Australian Minerals Regional Hub in Perth, Western Australia.

PhotonAssay provides enhanced analysis of gold, silver and complementary elements in as little as two minutes, improving turnaround time, SGS said.

“SGS is at the forefront of innovation excellence in the minerals and mining sectors with leading automation across FTIR, pXRF, NIR and now PhotonAssay, which will support mining and exploration customers with faster, safer and more environmentally friendly analysis,” SGS said.

Chrysos Corporation Chief Executive, Dirk Treasure, said: “Chrysos is excited to be working with the SGS team. The installation of this new PhotonAssay unit at their cutting-edge facility in Perth reflects the desire of both organisations to deliver unparalleled levels of customer service through faster, safer and more sustainable assaying technologies.”

Hitting samples with high-energy X-rays, Chrysos PhotonAssay causes excitation of atomic nuclei allowing rapid and enhanced analysis of gold, silver and complementary elements. Importantly, the non-destructive process allows large samples of up to 500 g to be measured and provides a “true” bulk reading independent of the chemical or physical form of the sample, the companies said. The technology is also measurably safer and more environmentally friendly than previous assay processes, aligning with SGS’s core principle of achieving a better, safer, and more interconnected world, SGS said.

Derick Govender, Executive Vice President, Natural Resources, SGS, said: “As the leading testing, inspection, and certification service provider to the mining industry globally, SGS continues to seek new, innovative and sustainable solutions to further enhance our services to our customers. In adopting Chrysos PhotonAssay technology at our Perth facility, SGS will continue to work on further deployments of this technology within our global network. Our team’s technical expertise and insight into our customer`s value chain end-to-end is one of our key advantages that allows us to develop innovative solutions.”

Chrysos Corp has already worked with MinAnalytical, MSALABS and Intertek on deploying PhotonAssay units at labs.

SGS expands Spijkenisse facility on rising metals and minerals testing demand

SGS metals and minerals trade commodities group has started expanding its lab facilities in Spijkenisse, Rotterdam, following a rising demand for testing services.

The company began the construction of its new, state-of-the-art laboratory in April.

This expansion, which is expected to be completed by December 2021, will double the capacity and improve turnaround times of the company’s current operations.

SGS’ laboratory in Spijkenisse, located near the port of Rotterdam, already offers a broad range of testing services for the metals and minerals industry. It performs analyses on non-ferrous and ferrous products such as ores, industrial minerals, concentrates, intermediate products and high-purity metals. Services include, among others, sample preparation, TML/FMP, wet chemistry analysis, XRF, ICP OES, AAS, electrogravimetry and fire assay.

Frans van Croonenborg, SGS Business Manager Natural Resources, Minerals Commodities, Benelux and Germany, said: “By continuing to invest in the laboratory’s facilities, we are committing to increase our operational excellence – provide our customers with fast and wide-ranging testing services. Our employees are excited about the new facility and SGS’s continued commitment to offer the latest technologies to the global industry.”

Kamoa-Kakula copper production kicks off

Ivanhoe Mines has announced the start of copper concentrate production at the Phase 1, 3.8 Mt/y Kamoa-Kakula copper mine in the Democratic Republic of the Congo, several months ahead of schedule.

First ore was introduced into the concentrator plant on May 20 to perform initial hot commissioning tests on the ball mills and other processing equipment. The initial mill feed grade reached approximately 4% Cu shortly after start-up.

As of May 25, 5-6% Cu ore was being conveyed directly from Kakula’s underground mining operations to the run-of-mine stockpile and the concentrator. Based on extensive test work, the concentrator is expected to produce a very high-grade, clean concentrate grading approximately 57% Cu, with extremely low arsenic levels, the company says.

Robert Friedland, Ivanhoe Mines Co-Chairman, said: “This is a historic moment for Ivanhoe Mines and the Democratic Republic of Congo. Discovering and delivering a copper province of this scale, grade and outstanding environmental, social and governance credentials, ahead of schedule and on budget, is a unicorn in the copper mining business. This accomplishment reflects the outstanding cooperation of thousands of individuals, and all of our joint-venture partners at Kamoa-Kakula.”

He added: “Although this exploration journey started well over two decades ago, it also is noteworthy that the Kakula deposit itself was discovered a little over five years ago, which is remarkable progress by the mining industry’s glacial standards from first drill hole to a new major mining operation.”

The initiation of production puts Ivanhoe on the path to establish Kamoa-Kakula as the second largest copper mining complex in the world, according to Friedland.

“What really excites our geologists is the profound potential to find additional Kamoa-Kakula-like copper discoveries on our massive Western Foreland exploration licences right next door, in an identical geologic setting,” he said.

Co-Chairman, Miles Sun, added: “The inception of Phase 1 is the birth of a copper complex that will benefit generations to come, and we very much look forward to the upcoming phases of expansion and exploration opportunities.

“Huge congratulations to the entire Ivanhoe Mines team and a roaring applause to all the hard-working suppliers and contractors for collectively completing this mammoth undertaking!”

Ivanhoe’s guidance for contained copper in concentrate expected to be produced by the Kamoa-Kakula project for the balance of 2021 assumes a ramp-up from first production in line with published technical disclosures, with contained copper in concentrate output of 80,000-95,000 t.

In April, the Kakula Mine mined 357,000 t of ore grading 5.7% Cu, including 121,000 t grading 8.4% Cu from the mine’s high-grade centre.

Kakula, Ivanhoe says, is projected to be the world’s highest-grade major copper mine, with an initial mining rate of 3.8 Mt/y, ramping up to 7.6 Mt/y in the September quarter of 2022. Phase 1 is expected to produce approximately 200,000 t/y of copper, and phases 1 and 2 combined are forecast to produce approximately 400,000 t/y of copper.

Based on independent benchmarking, the project’s phased expansion scenario to 19 Mt/y would position Kamoa-Kakula as the world’s second-largest copper mining complex, with peak annual copper production of more than 800,000 t.

Given the current copper price environment, Ivanhoe and its partner Zijin are exploring the acceleration of the Kamoa-Kakula Phase 3 concentrator expansion from 7.6 Mt/y to 11.4 Mt/y, which may be fed from expanded mining operations at Kansoko, or new mining areas at Kamoa North (including the Bonanza Zone) and Kakula West.

The Kamoa-Kakula copper project is a joint venture between Ivanhoe Mines (39.6%), Zijin Mining Group (39.6%), Crystal River Global Ltd (0.8%) and the Government of the Democratic Republic of Congo (20%).

Alongside this announcement, the company confirmed that Kamoa Copper had appointed Société Générale de Surveillance (SGS) CONGO SA, an accredited laboratory service provider, for on-site analytical services. SGS is one of the world’s leading inspection, verification, testing and certification companies. The new assay laboratory is equipped with state-of-the-art equipment.

Results for various mine, exploration and processing sample types will be reported using a wide range of analytical techniques that are specifically selected to provide accurate and precise results within the time required to efficiently control concentrator and mine processes.

Process control samples will be analysed using portable X-ray Fluorescence (pXRF) devices with a quick turnaround time for concentrator plant monitoring and control. Metal accounting samples will be analysed by using two simultaneous ICP-OES multi-element instruments. The dual measurement mode of the ICP-OES instrumentation enables the analysis of critical elements such as mercury, arsenic, lead, etc by providing high measurement sensitivity while the combination of two-sample digestion methods (fusion and acid digestion) will cover a wide range of analytic levels, Ivanhoe said.

The high-grade copper samples will be analysed using the classical iodide titration method, which provides good accuracy and precision that is required for the dispatch samples, the company said. Convenient and flexible potentiometric auto titrators provide efficient and accurate results that are fully traceable to international methods and standards.

Jervois Mining looks to POX leaching to boost SMP nickel-cobalt refinery recoveries

Jervois Mining says it plans to integrate a pressure oxidation leach (POX) circuit into the São Miguel Paulista nickel-cobalt refinery in Brazil.

Jervois paid the first tranche towards its acquisition of SMP refinery in December after announcing plans to acquire the refinery in September 2020. The acquisition aims to complement its 100%-owned Idaho Cobalt Operations (ICO) in the US, transforming Jervois into a vertically integrated producer capable of refining cobalt and nickel.

The company appointed Australia-based Elemental Engineering to commence sysCAD modelling of the SMP refinery flowsheet for optimisation of product integration, including hydroxides and carbonate products, oxides and sulphide concentrates as part of a feasibility study (FS) for SMP’s restart.

As a result of Elemental’s work, Jervois has determined it shall integrate a POX leach circuit at the refinery.

“The inclusion of the POX autoclave offers a number of advantages compared to roasting concentrates, namely high metal recovery, low overall operating costs, enhanced ESG metrics due to lower emissions and energy usage, improved refined product purity and compact installation footprint on site,” the company said. “Preliminary POX sighter testwork at SGS Perth Western Australia, in conjunction with Elemental’s work, returned satisfactory results.”

While POX comes with a higher capital expense than roasting alternatives, it is a commercially demonstrated technology with low technical risk, allowing Jervois to leverage its recently appointed commercial team, Jervois said. A POX autoclave better compliments the refinery flowsheet, unlocks sunk capital by debottlenecking the existing leach capacity and adds significant flexibility to future refinery feed options, it added.

Jervois will process sulphide concentrate produced from ICO via this integrated POX leach circuit, with Jervois’ commercial team actively pursuing supply contracts for nickel and cobalt intermediate products. The introduction of a POX autoclave opens up greater capacity to leach other hydroxide and carbonate feed products to maximise existing refinery capacity, the company said.

Third-party concentrates can also be potentially introduced into the POX to process with Jervois’s ICO concentrates. Early discussions with potential third-party suppliers of sulphide-based concentrates have been positive, with the company now openly engaging with suppliers to optimise the sizing and economics of front-end pre-treatment.

As part of this, a decision has been made to reserve the maximum amount of copper capacity at SMP refinery for third parties. A consequence is that ICO construction is being advanced on the basis of the production of separated cobalt and copper concentrates. Jervois’s engineering advisers, DRA Global and M3 Engineering, completed the ICO BFS on both bulk and separated concentrate flowsheets, with construction plans being implemented based on the production of cobalt concentrate (containing gold and low in copper) and a copper concentrate. Commercial terms were obtained for both separated products as part of the BFS.

Jervois says it and Companhia Brasileira de Alumínio (CBA), the current owner of the SMP refinery, continue to work expeditiously towards closing Jervois’ acquisition of SMP.

Jervois plans a measured and staged approach to the refinery facility restart. Initial refurbishment works will be completed to progress the processing of intermediate hydroxide and carbonate products followed by the integration of the POX leach circuit to align with ICO commissioning, it said.

Jervois is in discussions with suitably qualified engineering contractors that have the appropriate nickel and cobalt refining experience, have a significant presence in Brazil, and have recently completed a POX and metals plant installation, to award the BFS for the refinery restart. This formal tender process is underway.
