| Abstract: | 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. |
