摘　　要：针对某低品位碳酸锰矿,开展了磁、重、浮选以及联合工艺选矿对比实验研究。结果表明,强磁选是处理该矿的较佳工艺流程,通过一次粗选、两次精选、一次扫选、一次精选尾矿再磨磁选的实验流程,最终可获得锰品位21.04%,回收率75.55%的锰精矿产品,该实验研究为同类锰矿的开发提供了依据。According to characteristics of a low-grade manganese carbonate ore,it made a respective use of high gradient magnetic separation and shaker gravity separation,as well as experimental study on flotation process of the ore.Experimental results showed that wet high-intensity magnetic separation was the reasonable way to deal with the mine.The magnetic concentrate with Mn grade of 21.04%and Mn recovery of 75.55%could be obtained by adopting high intensity process of one-stage roughing,one-stage scavenging,two-stage cleaning,and regrinding magnetic separation of cleaning tailings.The experimental study provides a basis for the development of similar manganese ores.
