    leaching with cyanide. Gold recovery is usually around 80%, but can be as low as 60%. Recoveries can be improved to 95-99% 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

  • Gold extraction Wikipedia

    Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold

  • Processing, smelting and refining gold World Gold

    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 and solvent in large tanks equipped with agitators.
