摘要
报道了以软锰矿和锌精矿为原料，在盐酸介质中同槽浸出与除铁、溶液净化、锌锰分离、提取化学二氧化锰与活性氧化锌的新工艺。在适宜的工艺条件下，可以取得较好的技术指标。
A new technique for preparation of chemical manganese dioxide and activated zinc oxide from pyrolusite and zinc concentrate in chlorhydic acid medium was reported. The technique includes leaching and removal of iron, purifying, zinc-manganese seperation, extraction activated zinc oxide and CMD from the solution. In the optimum technological conditions, the better technological index can be obtained.
