There is 538. 51 mg/L Sb and 395. 91 mg/L Cu in a leachate from a smelting plant in Hechi,Guangxi Prov-ince. Antimony recovery by hydrolysis precipitation method,copper recovery by Na2 S precipitation from residual liquid from an-timony precipitation on the leachate experiment results showed that antimony hydrolysis precipitation at the stirring speed of 150 r/min,reaction at 56 ℃for 20 min,final pH=3. 15,precipitation antimony products with antimony grade and precipitation rate of 10. 35%,98. 23% is obtained. Residual liquid from antimony precipitation with Na2 S dosage of 2. 5 g/L,stirring speed of 150 r/min,reaction at 50 ℃for 10 min,stewing for 20 min and then enduring filtration,precipitation copper products with copper grade and precipitation rate of 36. 92%,98. 38% is obtained. The tests proved that fractional precipitation is a feasible method to recycle antimony,copper from the leachate.
