performance of gold ore liner

Processing, smelting and refining gold World Gold Council

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.

A Method for Leaching or Dissolving Gold from Ores or

native gold from gold-bearing ores. It has been known for more than a century that alkaline solutions of alkali-metal cyanides (e.g., NaCN, KCN) dissolve gold under aerated conditions. The dis-solution of metallic gold is due to the strong complexing capabilities of cya-nide anions combined with the oxidizing properties of the dissolved molecular
