Core Resources has announced that its proprietary Toowong ProcessTM Technology has been acquired by “a leading resources group.” The process safely removes arsenic, antimony and other impurities from copper concentrates. At the heart of the process is a patented Alkaline Leaching (AL) step that selectively solubilises key penalty impurities. The process produces a clean premium[…]

Metso Outotec says it is re-introducing its TankCell® offering – the largest of its kind on the market – in an effort to further provide efficient and economical plant design with high availability and reduced plant footprint for any application. Since the 1990s, Metso Outotec has delivered nearly 8,000 TankCell flotation cells to mining customers[…]

PT Vale Indonesia Tbk has again agreed to collaborate with Zhejiang Huayou Cobalt Co (Huayou) to develop a nickel smelter with High Pressure Acid Leaching (HPAL) technology in Sorowako. The two parties’ cooperation has started early this year and Huayou conducted the feasibility study. The feasibility study has been concluded with a positive outcome. With[…]

Sixth Wave Innovations Inc says it has signed a three-phase test and implementation contract that will field its patented IXOS® molecular imprinted polymer for extraction and purification of gold and silver at Magnus Resources’ majority-owned Penhalonga gold mine in Zimbabwe. Additionally, Magnus Resources plans to build and deploy three smaller processing plants to assist regional[…]

TNG Limited, an Australia-based resources company, has awarded Metso Outotec a study looking at reducing Mount Peake Ti-V magnetite concentrate using Circored™ technology, which uses hydrogen as its only reductant source. As part of the study, Metso Outotec will perform a techno-economic assessment to integrate Circored technology into TNG’s TIVAN® process that provides for the[…]

Copperstone Resources AB and GreenIron H2 AB are starting a joint development project, based on GreenIron’s fossil-free reduction process and Copperstone’s future by-product flows from planned copper and magnetite mining. The project intends to optimise material handling both before and after GreenIron’s process. Copperstone will contribute with material handling and analysis and GreenIron will contribute[…]

McEwen Copper’s Los Azules project in Argentina looks like becoming the latest potential leaching asset put under the Nuton® Technologies microscope after the signing of a collaboration agreement between McEwen Copper and Nuton. The agreement, tied to an oversubscribed $81.85 million offering of McEwen Copper shares, will see Nuton, a Rio Tinto Venture, test its[…]

The Copper Mark, the assurance framework to promote responsible practices and demonstrate the copper industry’s contribution to the United Nations Sustainable Development Goals, has been awarded to two more sites from Antofagasta and Southern Peaks Mining. With these additions, over 20% of the world’s global mined copper production now comes from Copper Mark-awarded sites. In[…]

Chaarat Gold has announced the completion of the first phase metallurgical test program performed by SGS Lakefield on its Kyzyltash gold project, in Kyrgyzstan, which showed similar first stage recoveries from both pressure oxidation (POX) and Albion™ technologies. The project has a current JORC-compliant measured, indicated and inferred sulphide resource of 5.4 Moz of gold[…]

Weir Minerals and Eriez Flotation have announced a cooperative agreement to design and develop coarse particle flotation (CPF) systems. Course particle flotation facilitates more efficient separation, while also reducing water and energy consumption and producing safer tailings. It has been proven at the likes of Anglo American’s El Soldado mine, Newcrest’s Cadia operation and Capstone[…]
