摘要

Reductive ammonia leaching method was used to recover Cu and Co from heterogenite. The influences of the reductant quantity, leaching temperature, the concentration ratio of NH_3 to (NH_4)_2SO_4, leaching time and liquid-solid (L/S) ratio on leaching rate of cobalt and copper were investigated. The optimal conditions at which the leaching rate of copper and cobalt were 96.07%, 98.24% respectively and that of Fe, Mg and Al were almost 0 were as follows: time = 5 h, T = 50°C, the amount of ammonia is 1.2 times of theorrtical, C(NH_3):C [(NH_4)_2SO_4] =1:3, L/S ratio = 3:1, and the dosage of Na_2SO_3 is 0.5 times of the heterogenite's mass.
