摘要
我国钾盐资源严重不足 ,开展富钾岩石资源利用的研究 ,应成为解决我国钾资源紧缺的一个重要途径。国外这方面研究已有一些可资借鉴的成果。我国钾长石、富钾岩石、绿豆岩、霞石、明矾石等富钾矿物及岩石资源丰富。目前探索其利用途径有直接法、浸取法、挥发法、生物法等 ,均取得了不同程度的成效 ,积极开展这方面的研究对充分实现资源的综合开发利用、治理污染等均具有重要意义。
China is seriously short of potash resource, a problem that can get solved through research on how to develop and utilize potassium-rich rock resource. It is rich in potassium-bearing minerals and rocks, such as K-feldspar, potassium-rich rock, potassium-containing tuff, nepheline, alunite, and so on. Today, methods for extracting potassium from these rocks and minerals include direct extraction, leaching, volatilization, biological extraction, etc., each with a certain efficiency. Actively conducting studies on tapping and using potassium-rich rock resource can not only realize its comprehensive utilization but eliminate environmental pollution.
