Processing, smelting and refining gold World Gold Council

More gold is recovered by cyanidation than by any other process. In cyanidation, metallic gold isoxidised and dissolved in an alkalinecyanide solution. When gold dissolution is complete, thegold-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 …

However, gold is readily dissolved in a number of solvents, includingoxidizing solutions of hydrochloric acid and dilute solutions of sodium cyanide. Gold readily dissolves in these solvents because of the formation of complex ions that are very stable. Gold (Au) melts at a temperature of 1,064° C (1,947° F).
