摘　　要：磷和钾是我国工农业生产的重要战略资源,但磷矿品位低和钾资源匮乏的现状一直困扰着我国经济的发展。针对汉源和宜昌等地储量大、经济价值高的磷钾矿,总结了其利用方式及研究成果,提出现有技术的不足和存在的问题,认为优化酸解工艺路线和研究适用于酸解法的新型表面活性剂是未来磷钾矿利用的重要研究方向。Phosphorus and potassium are important strategic resources for China’s industrial and agricultural production,but the current situation of low grade phosphorus rock and lack of potassium resources has been perplexing China’s economic development.Aiming at the phosphorus and potassium rock with large reserves and high economic value in Hanyuan and Yichang,the research results of their utilization mode are summarized,the existing technical shortcomings and existing problems are put forward.It is considered that optimizing the acidolysis process route and development new surfactants suitable for acidolysis are important research directions for the utilization of phosphorus and potassium rock in the future.
