FLSmidth says it has sold three system packages to Gold Fields for its greenfield Salares Norte project in Chile. The large downstream gold product line project comprises, FLSmidth says, three complete process islands: a Merrill Crowe, an AARL (Anglo American Research Laboratories) elution circuit and a refinery. The process plant will treat 2 Mt/y of[…]

High-grade, simple orebodies are becoming harder to find, forcing mines to process lower grade and more complex deposits. Being able to quantify the mineralogy of incoming ore-bearing rocks is critical to pre-planning and optimising processing operations as well as controlling costs. Most types of mineral processing activities can benefit from access to accurate daily mineralogy[…]

FLSmidth is to supply the key roasting kiln section of the Gabanintha vanadium project process plant as part of a binding notice of award the OEM has signed with project owner Technology Metals Australia. Technology Metals Australia developed a relationship with FLSmidth during the definitive feasibility study (DFS) phase of the Gabanintha project, with the[…]

By Wolfgang Baum* Dan Gleeson wrote in International Mining April 2020, “…near identical flowsheets have remained the status quo for decades, with the only variation tending to be how many pieces of conventional equipment are used, as opposed to what new innovations are slotted in up- or downstream of primary crushing”. It is puzzling that,[…]

Eriez’s Flotation Division continues to benefit from its investments in testing capabilities at its Central Test Lab (CTL) in Erie, Pennsylvania, with the company saying its technical services business has doubled since 2015. Eriez maintains an assortment of bench and pilot-scale equipment for both laboratory and in-field evaluations, with the flotation division conducting on-site testing[…]

Green hydrogen from an RWE Generation electrolyser could help thyssenkrupp Steel Europe sustainably reduce CO2 emissions from steel production in the future. The energy company and the steel producer have agreed to work together towards a longer-term hydrogen partnership. The first hydrogen is set to flow to the Duisburg steel mill by the middle of[…]

Dundee Sustainable Technologies (DST) has hit a new milestone, with results from metallurgical testing on mineralised samples from a top tier gold producer achieving extraction yields of up to 95.6% with the help of its cyanide alternative CLEVR ProcessTM. DST received a circa-10 kg sample of material from an operating gold mine in South America,[…]

While the effects of COVID-19 continue to be felt across the mining equipment, technology and services (METS) sector, the time away from the office or mine site has enabled many within the industry to carry out work that could lead the industry into a whole new growth cycle. The jury is out on when such[…]

Metso is looking to increase access to and improve the visualisation of mining process flowsheets with a new tool that could ultimately see more of its equipment end up at mine sites. My Plant Planner offers engineering customers and mining end users the ability to model a flowsheet after inputting certain key parameters of their[…]

SSAB, LKAB and Vattenfall are taking another important step in their fossil-free steelmaking journey with preparations now underway for the construction of a demonstration plant on an industrial scale for its HYBRIT initiative. The companies have also started consultations for deciding on placement of this demo plant in Norrbotten, Sweden. The objective of the joint[…]
