The ore contained 0.14g/t of gold, 8.93% of copper, 80.0g/t of silver, 0.28% of lead, 0.45% of zinc and 0.54% of sulfur. The valuable elements that can be recovered were copper and silver. The useful elements in the ore were mainly copper and silver, and the copper-bearing minerals were mainly bornite, chalcopyrite, native copper, cuprite, malachite and so on.
After the grinding, the grinding particle size was -200 mesh (70.0%). The sulfide ore was sent to one-stage roughing, two-stage scavenging, and the oxidized ore was sent to one-stage roughing, three-stage scavenging and two-stage concentration. The final concentrate was the mixed concentrate.
