ENRICHMENT OF COPPER-ANTIMONY-SILVER POLYMETALLIC ORES
The article deals with the results of experiments on the enrichment of polymetallic ores of the Akdzhilginsky deposit. By collective flotation, the copper-antimony-silver collective concentrate is extracted in a complex manner. Valuable minerals tetrahedrite, chalcopyrite are encrusted in the form of small and thin granules, but their structure is quite complex. The main metallic elements, copper and antimony, are formed in the form of sulfides or oxides. The main vein mineral is quartz. Under the condition of the ore grinding fineness recommended for the experiment of 90.3% -0.074 mm, the technology of collective flotation is used, during which a copper-antimony-silver collective concentrate and tailings are obtained. The tailings of collective flotation are dump tails.
