滇池地区中低品位胶磷矿重浮选矿试验研究

Test on gravity-flotationcomplex process of mid-low gradephosphate rock in Dianchi region

根据滇池地区晋宁、昆阳、海口中低品位胶磷矿的矿物特性,确定以重浮联合流程选别中低品位胶磷矿。结果表明:利用重选预选减少入浮选量一定程度上降低了选矿成本,减小了浮选对环境的污染。

According to the mineral characteristics of mid-low grade phosphate rock in Jinning, Kunyang, Haikou areas, the gravity-flotation complex process was selected. The results showed that gravity separation pretreatment could reduce ore quantity of entering the flotation and decrease the beneficiation cost, and also reduce the pollution of flotation.
