摘　　要：利用光卤石、氯化钠在特殊捕收剂上的吸附能力不同,使光卤石与氯化钠通过浮选分离。所得的低钠光卤石加水分解,得到固相氯化钾和分解母液。该工艺的特点是产品纯度高,收率较高,物理性能良好,对原矿的适应性强,制取的氯化钾产品品位高。Use different adsorption capacity of carnallite and sodium chloride on special collectors, carnallite and sodium chloride can be separated by flotation separation. The resulting low sodium carnallite was decomposed by adding water,solid potassium chloride and decomposed filtrate were obtained. The process is characterized by high purity,high yield,good physical properties,strong adaptability of the ore, preparation of high-grade potassium chloride products.
