摘　　要：针对贵州织金磷矿石,采用"阶段磨矿,阶段选别"的流程进行试验,结果表明:磨矿细度-0.074 mm为75.00%时,精矿含P2O533.43%,含MgO2.08%,P2O5回收率达84.41%。Tests on Zhijin phosphate ore in Guizhou were carried out by using the flotation circuit of ＂stage grinding multi-stage separation ＂. The results showed that when the particle size （ - 0. 074 mm） reached 75. 0096, the concentrate with P2O5 33. 4396, MgO 2.0896 was obtained. The recovery of P2O5 is 84.4196.
