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.

Also disclosed are methods of solution mining that include injecting an aqueous solution into an …
Feb 03, 2020· Wyoming is home to the largest trona deposit in the U.S., and the Sweetwater mines produce more than 17 million tons of trona annually, Deti said. "We export about 50 percent of that right now, and I do think you'll see the demand go up in coming years," he added. "It's really a bright spot for Wyoming mining right now.".
It comprises a group of claims located 10 miles northeast of Trona, on the west slope of the Slate Range of mountains; owner, California Queen Mining Co.; C. S. McCarthy, Trona, Calif. Slate Range District. This district is situated on the west slope of the Slate Range, 9 miles north and east of Trona, in the southern part of Inyo County.
mine. Our experience from many mining projects indicates that well-designed and executed mine water control programs can substantially improve mining conditions by increasing the efficiency of rubber-tired vehicles, creating a safer environment by working in dry, instead wet conditions, and, therefore, decrease the cost of operations.
Searles Lake is an endorheic dry lake in the Searles Valley of the Mojave Desert, in northwestern San Bernardino County, California.The lake in the past was also called Slate Range Lake and Borax Lake..

In addition, the trona in mining beds has a higher concentration of soda ash as compared to the trona mined at other locations in the Green River Basin, which is typically imbedded or mixed with greater amounts of halite and other impurities. Ciner's trona ore is generally composed of approximately 80% to 89% pure trona.
