Thermal Enrichment of Gold-Bearing Sulfide Mineral Material Using Centrifugal Flotation

Depleted gold-bearing sulfide mineral materials can be employed in cement production, construction industry, road construction, and other sectors of the national economy. This will enable metallurgical enterprises to switch to low-waste or nonwaste technologies. Research on and practice of ore beneficiation with a high degree of sulfidity reveal that gold recovery is directly dependent on the degree of ore sulfidity and the content of the main ore sulfide minerals. To increase the efficiency of gold recovery, a device for the enrichment of gold-bearing sulfide materials using centrifugal flotation is developed.
