Based in Overland Park, Kansas, Searles Valley Minerals is a mining company that processes brine solutions from Searles Lake to produce boric acid, sodium carbonate, sodium sulfate, several specialty borates, and salt. The company operates three facilities in Searles Valley using a solution-mining approach described as environmentally oriented, rather than traditional open-pit methods, and it employs a few hundred people. Its products serve industrial and agricultural markets, with customers relying on the minerals for a range of everyday applications—soda ash and borates in glass and automotive components, salt for industrial laundries, and sodium sulfate for dye and detergent production. Borates support high-technology uses such as displays, electronic parts, and coatings, while specialty borates appear in fire retardants, fiberglass insulation, and wood treatment. In 2025, GlassPoint Solar announced a partnership with Searles Valley Minerals to decarbonize industrial process heat and enhance U.S. mineral competitiveness.
