【摘要】 用黄铁矿作还原剂 (燃料 )与低品位高锰矿混合 ,在立窑中焙烧 ,经水和溶液浸出、净化、合成、过滤等工序生产人造碳酸锰等矿产品。用软锰矿浆吸收废气中二氧化硫更多还原

【Abstract】 A commercial grade of manganese carbonate can be prepared through a process of co calcining reductant pyrite(fuel)and low grade black manganese(high content of phosphur)in a vertical kiln,followed by leaching with water or weak acid liquid,decontaminating,synthesizing and then filting.Sulphur dioxide gas is absorbed and dissolved into the ore pulp of purolusites.更多还原
