摘要
Abstract
The removal of copper and nickel from complex copper anode slime by oxygen pressure acid leaching was studied.The effects of reaction temperature,sulfuric acid concentration,liquid-solid ratio,stirring speed,oxygen partial pressure and reaction time on the removal of copper and nickel were investigated.The results show that,at the following optimal conditions,including anode slime of 30.0 g,1.5 mol/L sulfuric acid solution of 300 mL,liquid-solid ratio of 10(mL:g),reaction temperature of 160 °C,oxygen partial pressure of 0.2 MPa,stirring speed of 600 rpm,and leaching time of 3 h,the leaching rates of Cu and Ni can reach 99.26%and 95.36%,respectively,while the leaching rates of Sb and Bi were only 1.33%and 0.59%,Sn was hardly leached.The leaching solution can be returned to the electrolytic purification system to recover Cu and Ni,and the enrichment of high-value metals(such as Sn,Sb,Bi and precious metals)were nearly 2.7 times.关键词
