某含银低品位铁锰矿石选矿工艺研究

摘要

Based on the ore properties of a low-grade Fe-Mn ore containing silver form Inner Mongolia,a combined process of high intensity magnetic separation-flotation separation was carried out.The recovery of TFe reached 81.25％,while the recovery of Mn was 82.12％ in a Fe-Mn concentrate.The silver was recovered both in Fe-Mn concentrates and silver concentrates,and the total recovery of silver were 87.04％.The quality of concentrates met the requirements of subsequent smelting.The mineral processing experiment achieved ideal effect of separation.%针对内蒙某含银低品位铁锰氧化矿石的矿石性质,采用“强磁选铁锰—浮选选银”联合工艺流程进行选别.铁锰精矿中TFe回收率达81.25％,Mn回收率达82.12％,Ag在铁锰精矿及银精矿中总回收率为87.04％,精矿质量达到后续冶炼要求,选矿试验取得较理想效果.
