摘  要:
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%

摘  要:
Because the raw ore of flotation is with the more sources and unstable property, the quality of concentrate is unstable,its yield and recovery rate are low. The process conditions of each phosphate rock are analyzed by reverse flotation;The raw ore is matched based on respective property,then is treated with reverse flotation. The results show: by ore matching, the requirement of grinding fineness is decreased, the consumption of agent is declined, the quality of concentrate is acceptable, the concentrate yield and recovery rate of P_2O_5 are high, the highest recovery rate of P_2O_5 is 90.25%.
