摘　　要：该工艺以察尔汗盐湖生产钾肥排放的尾盐为原料,利用含钾尾盐制取食品级氯化钾的方法,解决现有食品级氯化钾制备技术中存在工艺复杂和生产成本较高的问题,同时回收利用含钾尾盐中的氯化钾。既解决了察尔汗钾资源浪费的问题又解决了环保问题,实现察尔汗地区资源综合回收利用和循环利用发展之路。This process is to use the tail salt from the production of potassium fertilizer in Chaerhan Salt Lake as the raw material, and use the tail salt containing potassium to prepare food grade potassium chloride, so as to solve the problems of complex process and high production cost in the existing food grade potassium chloride preparation technology. At the same time, the recycling of potassium chloride in the tail salt containing potassium can not only solve the problem of resource waste of Chaerhan potassium, but also solve the problem of environmental protection Therefore, the comprehensive recovery and recycling of resources in Qarhan area can be realized.
