摘　　要：低品位氧化锰矿因无法直接酸浸,也不适宜采用传统火法还原,未能得到高效资源化利用,因此研究从低品位氧化锰矿中高效还原提锰具有重要意义。综述了氧化锰矿湿法还原技术的研究进展,重点总结了两矿加酸法、硫酸亚铁法、双氧水法、微生物浸出法、生物质还原浸出法和二氧化硫还原浸出法的优缺点,展望了湿法提锰的发展方向。Low grade manganese oxide ore is not suitable for direct acid leaching and traditional fire reduction technology,and can not be efficiently used as resources.Therefore,it is of great significance to extract manganese from low grade manganese oxide ore by efficient reduction.The research progress of wet reduction technology of manganese oxide ore is reviewed,and the advantages and disadvantages of acid addition method,ferrous sulfate method,hydrogen peroxide method,microbial leaching method,biomass reduction leaching method and sulfur dioxide reduction leaching method are emphatically summarized.The development direction of wet manganese extraction is prospeced.
