Gold extraction - Wikipedia en.wikipedia.orgIf the gold can not be concentrated for smelting, then it is leached by an aqueous solution: . The cyanide process is the industry standard.; Thiosulfate leaching has been proven to be effective on ores with high soluble copper values or ores which experience preg-robbing: the absorption by carbonaceous components which preferentially absorbs gold and gold-cyanide complexes.

Gold cyanidation - Wikipedia en.wikipedia.orgGold cyanidation also known as the cyanide process or the MacArthur-Forrest process is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction.
