中文摘要:

      研究了青海察尔汗盐湖水采光卤石矿生产氯化钾工艺中浮选除钙的方法。实验结果表明，分级浮选法除钙率平均迭88．16％，接近原矿的理论可除钙离子量91．58％。

英文摘要:

      The separation of calcium sulfate from water-mining carnallite by flotation for the production of KCl from Chaerhan Salt Lake was studied.Experimental results showed that an average rejection of 88.16% calcium sulfate could be achieved by a two-stage flotation operation,approaching the theoretical removal ratio of 91.58% from crude carnallite.
