云南磷化集团安宁矿业分公司浮选原矿来源点多、性质不稳定,造成磷精矿质量不稳定,磷精矿产率与回收率较低。通过对单矿点磷矿石进行单一反浮选试验,分析各种磷矿浮选条件;再根据各种磷矿的性质配矿后进行单一反浮选。结果表明,通过合理配矿,对磨矿细度要求降低,药剂用量减少,磷精矿质量合格,磷精矿产率与P_2O_5回收率均较高,P_2O_5回收率最高可达90.25% Yunnan Ningxia Phosphating Group Mining Branch of flotation more sources of origin, instability in nature, resulting in instability in the quality of phosphate concentrate, phosphate concentrate yield and recovery rate is low. Through single anti-flotation test on single ore point phosphate rock, various types of phosphate rock flotation conditions were analyzed; and then single anti-flotation was carried out according to the properties of various phosphate rock. The results showed that the requirement of grinding fineness decreased, the amount of chemical dosage reduced, the quality of phosphate concentrate was qualified, the recovery rate of phosphorus concentrate and P_2O_5 were higher, the recovery rate of P_2O_5 was up to 90.25%
