Refractory gold ores are classified as if a cyanidation process cannot recover more than 80% of gold even though fine grinding is used (Guay, 1981). The reason for the refractoriness of gold ores is either because gold is hosted in solid solution, or as colloidal particles, in pyrite and/or arsenopyrite.
