摘　　要：针对豫西南地区某低品位滑石矿的矿石特性,详细考察了磨矿细度、药剂种类及用量对浮选的影响。最终采用一次粗选、两次精选、中矿集中返回的闭路流程,得到了品位81.20%、回收率74.24%、白度81%的滑石精矿产品。This papers study on flotation of a lowgrade talcum in southwest of Henan province based on the ore properties.The test considered the grinding fineness,the collector dosage,the frother dosage,the depressor dosage and the inhibitor species in flotation.Using a process of two stage rougher flotation and one stage cleaning flotation in closed circuit test,the grade of the talc concentrate was 81.20%,with whiteness of 81% and a recovery of 74.24%.The middling were mixed and returned to the circuit.
