For gold and silver recovery from refractory ores, the activity of leaching microorganisms is applied only to dissolve metal sulfides like arsenopyrite bearing the precious metals prior to cyanidation treatment. For this process, the term bio-oxidation is used because the solubilized metals such as iron and arsenic are not of economic value.
