The majority of gold processing plants currently handle ores containing sulfide minerals. Gold in such ores is par-tially associated with sulfides and partially in a free state. Ores of this type are in most cases classified as refractory. The raw material for gold recovery is the gravity-flotation concentrate of ore enrichment.
