Improved Recoveries of Gold From Pyrite and Calcine by the …
Gold in many ores occurs in sulphides, which, if the gold is finely disseminated, renders the ore refractory and therefore not amenable to the simple process of milling and cyanidation. Traditional methods of treatment of these refractory ores is to produce a sulphidic flotation concentrate which is roasted to form a porous calcine from which the gold is recovered by …
