    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.

    How Metal Impurities Affect Gold Adsorption on Activated

    Activated carbon is known to adsorb organic solvents that affect the rate of loading rather than the equilibrium loading capacity of gold. Activated carbon will load small quantities of calcium carbonate, cyanide, hydroxide, and iron sulfide, which poisons the carbon, resulting in a loss of gold capacity.
