Potash solution mining is a process that involves extracting underground, water-soluble minerals such as potash and salt. This method of mining is preferred when the deposit is more than 1,000 meters below the surface and when the rock type is sedimentary. In such circumstances, the depth and rock type make conventional mining methods uneconomical.
Solution Mining is a proven and well-known technique where Potassium Chloride(KCl), commonly referred to as Potash, is dissolved by salt saturated brine injected into sylvinite layers to form caverns.
