For one copper?lead?silver?barium polymetallic ore from abroad, the mixed flotation of copper?lead and the tests of depress lead?coppe float, leach and gravity were conducted, ultimately, the dressing-metallurgy combination craft of copper lead mixed flotation?concentrate leaching?tailings gravity was employed, and the comprehensive utilization of copper, lead, silver and barium was realized. The results showed that raw ores contained 1.52% of copper, 7.84% of lead, 29.91% of barium sulfate, and 243.8 g/t of silver. A mixed concentrate containing 8.09% of copper with copper recovery rate of 85.50%, 47.21% of lead with lead recovery rate of 92.91%, 1389.4 g/t of silver with silver recovery rate of 87.93% was obtained after the processing of mixed flotation. Mixed copper and lead concentrate were leached under the following conditions: the leaching agent concentration 0.6 mol/L at room temperature (25℃), the liquid?solid mass ratio 4 and the extraction time 50 min. The leaching rates were copper 84.95%, lead 5.56%, and silver 21.04%. Moreover, a containing 1.54% of copper, 64.23% of lead and 1787.6 g/t of silver was produced. Finally, gravity separation of tabling was conducted for the leaching residue and a concentrate containing 95.37% of BaSO4 with a recovery rate of 35% was obtained.
