Abstract:

Potassium is an essential nutrient for crop growth.Potassium salt resources are mainly used for potassium fertilizer production.As a major consumer of potassium fertilizer,China is short of potassium resources.Potassium salt has been listed in the strategic mineral catalog,and the supply security of potassium salt resources is of great significance to the national security.The basic situation of global and domestic potassium resources were listed,the production and consumption situation of global and domestic potassium resources were analyzed,and the main production technology for preparing potash fertilizer from Chinese potash salt resources were introduced.Moreover,combined with the current situation of potassium salt production in China,some suggestions for the future potash salt industry in China were put forward,which included evaluation of the selected areas of continuous resources,continuous attention to the change of brine grade in salt lakes,and strengthening the research on technology.

Key words: potassium salt, resource, potash fertilizer, technology, exploitation and utilization
