  • A Review of the Cyanidation Treatment of Copper-Gold Ores and Concentrates

    The treatment of copper sulfide minerals containing a high percentage of oxide copper causes problems in the concentration process, decreasing the copper content. In order to increase the efficiency of the concentration process, it is necessary to treat the copper oxide component by leaching the grinded ore prior to the flotation, or by leaching the flotation tailings coming out from the
