Due to resource constraints and other reasons, China's potash supply and demand situation is not optimistic. On the one hand, because of the short-term improvement of potash production, on the other hand, the demand for potash has increased year by year, the contradiction between supply and demand has become increasingly sharp, and the gap is getting bigger and bigger. The situation of relying on imported potash to make up for domestic shortages is not easy to change in the long run. Therefore, China should not only strengthen the research and exploration investment of potash mines, but also strengthen the research of potash processing and processing technology of potash mines to improve the effective development and utilization of potash mines. The quality of potash mineral resources in China is poor, and the rich ore-rich resources are scarce. With the increase of mining intensity, the rich mineral resources are drastically reduced, and the development of potash mineral resources is gradually shifting from rich mine development to low-grade ore. Therefore, China should actively promote the resource conservation and comprehensive utilization technology of potash mines, and strive to improve the mining recovery rate, beneficiation recovery rate, and the associated resource utilization rate of key enterprises, and improve resource efficiency. Future research on the beneficiation method, beneficiation process and processing technology of potash mines should be further refined and detailed in the following aspects. (1) Continue to strengthen the work of potash ore dressing theory and basic research, and provide a solid theoretical basis and technical support for the development and utilization of potash mines in China. (2) Continue to carry out research on potash beneficiation process technology. With the reduction of rich ore resources, the selection of complex mines such as lean, fine and miscellaneous will complicate the beneficiation process technology, and it is necessary to develop a variety of adaptable processes. Fully improve the recovery rate and comprehensive utilization rate of potash resources. (3) Continue to strengthen the research on flotation reagents of potash ore. The diversification of alkyl carbon chain structure and multi-functionalization of collector molecules will become the future research direction. The combination drug will also be the potassium salt flotation agent. The direction of development. (4) The research on coarse-grained potassium salt flotation process and chemicals should be strengthened. The coarse-grained potassium fertilizer is popular in the market because it is not easy to be blown away by wind during the fertilization process, is not easy to agglomerate, has slow dissolution rate and long fertilizer efficiency. . With the development of cryolysis and crystallization technology of carnallite, it has become a reality to produce larger particles of KCl from carnallite ore, and with the high-quality potassium resources of Chinese enterprises going abroad to Laos, Congo, Canada and Central Asia. The pace of development of potassium salt resources in countries or regions will inevitably require the production of coarse-grained potassium salt flotation production technology, and the development and application of coarse-grained potassium salt flotation technology in China is still in its infancy, therefore, strengthening Research on coarse-grained potassium salt flotation process and pharmaceuticals is extremely urgent. (5) Strengthen the development and application research of equipment suitable for the characteristics and requirements of potash mineral processing. The development of mineral processing equipment to large-scale, automation, high-sorting and low-energy consumption is a trend. (6) Strengthen the research on the comprehensive recycling technology of symbiotic resources of potash ore, and the elements such as magnesium , sodium, boron , lithium , bromine , iodine , strontium and barium which are symbiotic with potassium have high comprehensive utilization value and effectively recycle potassium. The symbiotic resources in the salt mine will promote the sustainable development of mineral resources and produce huge economic, social and environmental benefits.

At present, China's proven potassium salt resources are about 1 billion tons (calculated by KCl, the same below), all of which are terrestrial salt lake potash, mainly distributed in modern salt lakes such as Qaidam Basin in Qinghai and Lop Nur in Xinjiang. Among them, the potash in the Qaidam Basin is mainly distributed in 11 modern salt lakes dominated by the Chaerhan Salt Lake, with a total geological reserve of 706 million tons. The salt lake in the northern valley of Lop Nur, Xinjiang, initially determined that the KCl geological reserves were 250 million tons. It also found that the total geological reserves and resources of KCl in Tibet's modern salt lakes were 0.47 billion tons. In addition, there are a small amount of potassium resources in Yunnan’s Sanyejing, Hubei Qianjiang and Inner Mongolia Salt Lakes.
