摘要
作为农业大国,可溶性钾矿资源短缺严重威胁了我国农业发展,因而利用储量丰富的难溶性钾矿提钾成为解决我国钾资源短缺的重要途径。本文介绍了难溶性钾长石提钾工艺技术研究现状,分类归纳了焙烧浸出法、压热法、低温分解法和微生物法在钾长石提钾综合利用方面的研究成果,最后阐述了钾长石提钾的研究前景,旨在为提钾工艺的研究提供一些理论依据。
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.
