copper cobalt processing

  • cobalt processing Uses, Supply, & Facts Britannica

    The most important sulfide sources, the copper-cobalt ores of Congo (Kinshasa) and Zambia, are processed in the conventional manner to produce a copper-cobalt concentrate. This is then treated by flotation to separate a cobalt-rich concentrate for treatment in the cobalt circuit.

    14.09.2020· Diversified chemicals group, Omnia Holdings, reports its Protea Mining Chemicals division has become the first in its field globally to develop a solution that helps copper and cobalt mines reduce product contamination (improving metal purity levels) and maximise throughput in the solvent extraction (SX) process.

    COBALT PROCESSING DEVELOPMENTS K G Fisher Bateman

    Cobalt is produced mostly as a by-product of other major metal extraction processes mainly copper and nickel and in recent decades the nickel industry has been the major source of cobalt. Now however the Democratic Republic of Congo (DRC) copper-cobalt production is coming to the fore once again after a 20-year period of decline.

    HYDROMETALLURGY 9 Cobalt processing options explored

    How Hydrometallurgy and the SX/EW Process Made

    In this process copper ore is mined, crushed, ground, concentrated, smelted and refined. The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copper-bearing minerals from it. To be applicable to this process, the ores must contain copper minerals in sulfide form

    Bulk flotation sequence: Under the bulk flotation process, a bulk Cu-Co flotation concentrate is produced at natural pH with xanthate, dithiophosphate and/or MBT, particularly if the copper mineralization is chalcocite. Copper is separated from the cobalt in the bulk concentrate by raising the pH up to at least 11 which depresses the cobalt minerals. Cobalt depression can be enhanced by small
