摘　　要：分析了胶磷矿的浮选过程特征,研究了离心力场在胶磷矿反浮选过程中的作用,结果表明在离心力场中存在着体积质量和粒度的分离,离心力场强化了微细粒级物料的矿化效果,提高了脱镁效果。The characteristics of flotation process of phosphate rock was analyzed, role of centrifugal force in reverse flotation of phosphate rock was studied. The results showed that minerals was separated by density and size under centrifugal field, mineralization effect of micro-fine mineral was enhanced and magnesium was removed effectively by means of the centrifugal field.
