摘　　要：本次以锡石和硅石为试样,用离心机选别,从理论到试验对细粒分选进行了分析研究。研究表明,试验结果与理论分析预测结果基本一致。试验中观察到锡石和硅石在高pH(pH=9)中比在低pH(pH=4)范围内分离效果要好得多,重矿物(锡石)回收率大于95%,品位可达80%。The author used cassitefite and silica as samples and separated them with centrifuge, then analyzed and studied the separation of small particles from theory to test. The result indicates that the test result basically matches the theoretical prediction result. It has been observed from the test that the separation of cassitefite and silica in high pH （pH = 9） was much better than that in low pH （pH = 4）. The recovery of heavy mineral （cassitefite） was over 95%, the grade could reach 80%.
