Oxidative precipitation recovers nickel and cobalt from ore

01/04/2020  Most existing process plants for nickel laterite ores use intermediate precipitation processes to recover the nickel and cobalt from the leach solution. The precipitation produces an intermediate product of nickel and cobalt, either as mixed sulfide precipitate (MSP) or mixed hydroxide precipitate (MHP), while largely separating nickel and cobalt from impurities such as manganese,

29/09/2017  The most well-known and mined ores are: nickel cobalt sulfide, copper cobalt sulfide, copper cobalt oxide, nickel cobalt laterite, and cobalt arsenic ores. Cobalt arsenides are processed using a roasting stage, followed by a pressure leach. Due to health and environmental issues almost all mines recovering these cobalt ores have been closed down.
