晋宁磷矿中低品位磷块岩选矿试验研究

Study on Beneficiation of Mid low grade Phosphate Rock

对晋宁磷矿Ⅳ矿段中低品位矿石进行了详细的选矿方法研究。提出采用简单的重—浮联合流程分选该矿石，小型试验和扩大试验都获得了较好的分选指标。将重选方法应用于晋宁磷矿尚属首次。

The beneficiation methods of the mid low grade phosphate rock in the section Ⅳ of Jinning Phoshpate Mine were studied in detail.Fairly good separation indexes were obtained by simple combination circuit of gravity separation and flotation in test and pilot test.It was the first time that gravity separation methed was applied to processing Jinning phosphate rock.
