| Abstract: | As a large agricultural country, the shortage of soluble potassium mineral resources has seriously threatened the development of agriculture in our country. Therefore, the method of extracting potassium from the rich insoluble potassium minerals has become an important way to solve the shortage of potassium resources. This article introduced the research status of the technology of extracting potassium from insoluble potash feldspar. The results of the comprehensive utilization of potash feldspar by roasting leaching method, autoclave method, low temperature decomposition method and microbial method were summarized by category. The prospects and significance of potassium research were introduced to provide the theoretical basis for the research direction of potassium extraction technology. |
