摘　　要：采用CPT浮选柱对青海格尔木藏格钾肥有限公司某车间的生产矿样做了浮选实验。研究发现,当给矿速度为600 m L/min、冲洗水流量为600 m L/min、空气流速为1 L/min时,氯化钾的品位和氯化钾的回收率最佳。通过一粗选二精选的浮选柱开路实验发现,浮选柱的浮选效果优于浮选机,氯化钾的品位比车间同一时段氯化钾品位高13.29%。实验结果可为进一步实验提供参考。A flotation experiment on core sample in a workshop of Geermu Zangge Potash Co.,Ltd. with CPT flotation column were carried out.The study found that when the feed speed was 600 m L/min,rinse water flow rate was 600 m L/min,the air flow rate was 1 L/min,the grade of potassium chloride and potassium chloride recovery were both the best.Through a roughing and two concentrating open experiment,it was found that the flotation effect of flotation column was better than the flotation machine,the grade of potassium chloride was 13.29% higher than a workshop at the same time.The experimental results can provide reference for further experiments.
