摘　　要：研究了工业硫酸锰湿法还原生产工艺,对反应条件及其影响因素进行了详细讨论。利用Fenton试剂的催化氧化作用对还原阶段的后期进行了关键性的改进,使锰矿中锰的利用率从现行工艺的83%提高至91%。新增产出大大高于所增加的原料投入,是一种非常值得推广应用的工业硫酸锰生产新工艺。The production technic of industrial manganese sulfate reduced by wet method was investigated . Meanwhile, the reaction conditions and effect factors were discussed . Since a critical improvement was adopted by catalytic oxidation of Fenton reagent in the post-stage of reduction, the utilization ratio of Mn in pyrolusite was increased from 83% up to 92%. It is a novel production technic of industrial manganese sulfate with prospective application.
