Solution Mining Research Institute

What is Solution Mining? SMRI views solution mining as mining of underground, water-soluble minerals, usually using one or more drilled wells to dissolve the minerals with water (not by using acids used in metal ore leaching). Minerals such as salt, potash, trona, and magnesium salts may be produced by pumping saturated fluid from underground caverns. The caverns are created by pumping out the

Application of the solution mining process to the Turkish ...

01/08/1996  The application of solution mining to a trona deposit can be achieved by two processes: sesquicarbonate and alkali extraction processes. The process conditions affect crystal shape, purity, size, uniformity, breakage resistance and the bulk density. These conditions can be evaluated in four steps for both of the processes: dissolution, filtration, crystallization and calcination. The main ...

FAQs Imperial Trona

Solution mining of trona is an environmentally friendly process where heated water is injected into the ore body and the resulting dissolved mineral is brought back to the surface for processing. Unlike the underground mining method where wastes are mined together along with ore, solution mining allows only the targeted mineral to be dissolved and released to the surface, leaving solid ...

Project Impacts Imperial Trona

Solution mining employs innovations that do not require miners to go underground. In addition, the surface impact is less invasive and can be easily reclaimed when mining is finished. This mining process involves injecting hot water underground to dissolve the natural trona layers to create a solution. Once the solution is extracted to the surface, the water is then evaporated from the ...
