摘　　要：介绍了采用新型捕收剂CB-805浮选回收某低品位钾混盐的工艺,获得了浮选精矿K+品位12.81%、回收率85.05%,精矿经兑卤转化后可获得K+品位19.92%的优质钾镁肥产品,实现了利用低品位钾混盐制取钾镁肥的目标。The paper introduces the process for flotation of low grade potassium salt mixtures using new flotation collector CB- 805 with the desirable effect achieved of flotation concentrate K＋ grade being 12.81%, K＋ recovery 85. 05 %. The concentrate un- dergone brine adding reaction can produce potash magnesium fer- tilizer with K＋ grade being 19.92% to achieve a target of produ- cing potash magnesium fertilizer by low grade potassium salt mixtures.
