| Abstract: | The production status of potassium fertilizer in China as well as the reserves and production status of potassium salt in Qinghai Salt Lake Industry Co., Ltd. are analyzed. The process, production method and technical index are introduced for potassium chloride production by cold decompositionflotation method, reverse flotation-cooling crystallization method, mixing brine-cooling crystallization method. The views is presented that the mechanism for strategic reserve of potassium fertilizer in China should be established, and the advanced technology of potassium fertilizer production should be imported to enhance international competitiveness. |
