The nickel leach solution is then purified to remove the aluminium and residual iron and then mixed with a reagent to produce a nickel intermediary product, which will either be a mixed nickel cobalt sulphide (MSP) or a mixed nickel cobalt hydroxide (MHP).
Covering a concise overview of the shifting landscape of the nickel processing industry, presented by METS Processing Engineer. This presentation explores the current options for treating sulphide and laterite ore bodies, James explained the limitations of current technology in today's climate.
The Ravensthorpe processing plant will employ an Enhanced Pressure Acid Leach (EPAL) hydrometallurgical process, which is a combination of pressure acid leach and atmospheric leach, producing a mixed nickel and cobalt hydroxide intermediate product (MHP).
up to 50 000 tonnes, with a further 14 000 tonnes of MHP (a mixed nickel cobalt hydroxide intermediate product) per annum (Ravensthorpe Nickel Operation 2008). BHP Billiton has opted for a residential workforce as opposed to a FIFO system. Offering this choice is seen in .

Jan 25, 2012· The MHP represents a more value concentrated product in that the approximately 1% nickel and % cobalt present in the original laterite ore are upgraded substantially in terms of their relative amounts in the MHP. Since the MHP has such a high valuable metal content, the feasibility of operating a centralized nickel and cobalt refinery increases.
COBALT PROCESSING DEVELOPMENTS K G Fisher Bateman Engineering Projects ABSTRACT Since the early years of cobalt production, and particularly during the last century, the major source of cobalt has changed whilst the world's cobalt usage has increased steadily. Cobalt is produced mostly as a byproduct of other major metal extraction

Mar 15, 2018· Ravensthorpe (100% First Quantum) History: Originally developed by BHP for US, first nickel was produced in Oct 2007. However following a little over 12months of operations (~20kt Ni production), losses had amounted to US678M (including Yabulu), driven primarily by a failure to reach nameplate capacity.
