  • FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES

    FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES

    2016-12-2895-99 by grinding to fairly fine particle size, gravity separation, cyanidation and flotation, all of which increase capital and operating costs. In some cases, oxidation of sulphide minerals is needed to liberate gold that is occluded within the sulphide matrix. Sulphides can be oxidized by several methods, and the overall costs are similar.
