摘　　要：针对锰离子(Mn2+)催化体系浸出硫化锌精矿过程,采用正交试验的方法研究了温度、时间、搅拌速度、液固比、氧压、Mn2+加入量等因素对锌浸出率的影响。在最佳工艺条件下,锌平均浸出率可达95%以上。To aim at leaching process of zinc sulfide in Mn^2 ＋ catalyst system, investigate the effect factors on leaching rate of zinc, such as leaching temperature, leaching time, stirring speed, liquid-solid ratio, oxygen pressure, the dosage of Mn^2＋ . The optimum operation condition is obtained by the orthogonal experiment. The leaching rate of zinc is more than 95 % under this condition.
