Spatial Distribution, Dynamic Changes and Controlling Factors of Solid Potash Minerals in Qarhan Salt Lake, Qinghai: Responses to Mining-Induced Conditions

Spatial Distribution, Dynamic Changes and Controlling Factors of Solid Potash Minerals in Qarhan Salt Lake, Qinghai: Responses to Mining-Induced Conditions

Potassium is crucial for agriculture and industry, with Qarhan Salt Lake being China’s largest potash production base, relying on solid potash liquefaction mining since 2006. This study investigated solid potash minerals in Qarhan using XRD, SEM, and PHREEQC, focusing on their types, spa...
