  • Gold Cyanidation ProcessMineral Processing Metallurgy

    The Cyanidation Process or CYANIDE LEACHING is most notably used in the recovery of gold. Safety and environmental concerns are of prime importance in the operation of a cyanidation plant. As we get farther into this type of recovery you will see why. The preparation of the ore for processing is similar to flotation. The ore must be ground to a specific size before it can be treated.

  • Processing smelting and refining gold World Gold Council

    In cyanidation metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore) cyanidation is accomplished by vat leaching which involves holding a slurry of ore
