The method of extraction of precious metals

Leaching of gold is first made with oxygenated water and then with gold-free oxygenated circulating solutions without addition of cyanide. Circulating solutions have pH= 8-10, C NaCN =0.1-0.2 g/l. Proposed method ensures high daily concentration of gold in production solutions of about 4-22 mg/l including increase of extraction of gold by 80-85%.
