杂卤石(2CaSO_4·K_2SO_4·MgSO_4·2H_2O)属低钾矿物,常与石膏共生,纯杂卤石含硫酸钾28.91％,如矿石中杂有石膏,钾的相对含量相应降低。目前我国钾盐资源短缺,如何以低成本从含钾矿石中提取钾盐是急待解决的课题。国家建材局地质研究所利用四川农乐杂卤石矿床的矿石,通过实验室试验找到提取可溶性硫酸钾的方法,此种方法流程简单,成本低,无尾矿,能直接从石膏、杂卤石混合矿石中取得硫酸钾、硫酸镁、硫酸钙、使
Polyhalite (2CaSO 4 · K 2 SO 4 · MgSO 4 · 2H 2 O) is a low potassium mineral, often symbiotic with gypsum, pure polyhalite containing 28.91% of potassium sulfate, such as gypsum mixed with ore, the relative content of potassium decreased accordingly. At present, China’s shortage of potash resources, how to extract potassium from low-cost potassium ore is an urgent issue to be solved. National Institute of Geology and Building Materials Bureau of the use of agricultural polyhalogen ore deposits, through laboratory tests to find soluble potassium sulfate extraction method, this method is simple, low cost, no tailings, can be directly from the gypsum, Get mixed potassium sulfate, magnesium sulfate, calcium sulfate
