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. Coarse 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[…]

Atalaya Mining reported its June quarter results today, noting that its continued balance sheet strength, which included net cash of €67.6 million ($69 million), continued to support its ongoing investment program. Included within this investment program is a project to recover high value copper and zinc metals from the complex sulphide concentrates sourced from Proyecto[…]

The technical team at Gekko Systems has released further data that, it says, supports the benefits of new technology that optimises carbon management systems in gold processing facilities. Optimising carbon management in the carbon-in-leach (CIL) circuit reduces gold solution losses and improves gold circuit recovery. This is essential for sites needing to offset higher inflationary[…]

Orica’s Investor Day, taking place last week, highlighted potential growth areas in one of the company’s less-publicised ‘verticals’, its Chemicals business. Mining, Quarry & Construction and Digital solutions often steal the headlines in quarterly updates, but Adam Hall, Group Executive & President of Asia & Chemicals, showed there is plenty going on within the company’s[…]

The ability to leach primary copper sulphides has, on many occasions, proved a hurdle too much, with conceptual work in the laboratory or pilot scale falling down on sub-economic or volatile recovery rates when working out in the field. This problem tends to result in one of two things: new capital-intensive concentrators are brought into[…]

US-based copper developer and near-term producer, Arizona Sonoran Copper Company Inc, has entered into a one-year exclusivity period with Nuton™, a Rio Tinto Venture that, at its core, is a portfolio of proprietary copper leach related technologies and capability. The exclusivity was triggered by successfully modelling the Cactus and Parks/Salyer ore samples and achieving the[…]

On June 28, Canadian mining major Teck Resources held a Sustainability Investors Roundtable to highlight elements of its sustainability strategy and leadership. One focus area was titled Low Carbon Transition and was presented by Sepanta Dorri, VP Decarbonization and Chris Adachi, Director Climate Change. They talked about haul trucks as one of Teck’s Carbon Reduction[…]

Draslovka Holding made its presence felt in the mining chemicals space about a year ago when it announced plans to acquire Chemours Company’s Mining Solutions business, a deal that has since seen it become one of the largest North American producers of solid sodium cyanide. This acquisition, completed in December for $521 million, also laid[…]

OZ Minerals recently set out to contribute to the acceleration of responsible metal production by the copper industry through the Ingenious Extraction innovator challenge, the outcomes of which have just been published. The in-depth document explores potential extraction methods and technologies, specifically utilising concentrate leaching techniques that can perform economically at scale. It also outlines[…]
