氧化锰细粒级尾矿选矿回收研究及实践

摘要

对福建省连城锰矿有限责任公司兰桥矿区氧化锰细粒级尾矿进行了磁选回收试验研究，确定回收细粒级尾矿生产工艺方案并投入使用，生产中单一磁选得到产率24．89％、锰品位40．32％、锰回收率74．97％的锰精矿，可作为回收细粒级锰矿的技术参考。%Fine grained tailings of manganese oxide was observed by magnetic separation experiment,which were produced in the Fujian Liancheng Lanqiao mine,the production process of fine tailings recycling was determined and put into use.Manganic concerntrate was obtained by single magnetic separation whose productivity was 24.89%,and grade was 40.32% with recovery rate 74.97%.The technology can be used as reference to recover fine ore.
