leaching plant thickener for ores low consumption

  • Cyanide Leaching Of Gold Mine Engineer.Com

    Most cyanide leaching is carried out at a alkaline pH of between 10 and 11, depending upon lab testing of individual ores and the optimum leaching/chemical use rates. The cyanide solution strength is also important in leaching gold, with the typical range of solution being in the 0.02% 0.05% NaCN.
