Study of the Technology for Gold Recovery from Gravity-Flotation …
The majority of gold processing plants currently handle ores containing sulfide minerals. Gold in such ores is partially 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.
