Rio Tinto Borax Mine
The Rio Tinto Boron Mine (formerly the U.S. Borax Boron Mine) Lua error in package.lua at line 80: module 'strict' not found. in Boron, California is California's largest open-pit mine and the largest borax mine in the world, producing nearly half the world's borates. Ore reserves are sufficient for production through at least 2050. It is operated by the Borax division of the Rio Tinto Group. [1][2][3]
The borax deposit here was discovered in 1913, by John K. Sukow, who when drilling for water found a deposit of what he believed to be gypsum, but further testing revealed that it was the colemanite form of borax. Francis Marion "Borax" Smith quickly bought the claim for his Pacific Coast Borax Company.[4][5] Mining at the site by shafts began in the 1920s. Pacific Coast Borax later became U.S. Borax, which subsequently opened the current open pit mine in 1957. U.S. Borax was later acquired by Rio Tinto Group, which continues to operate the mine today.
Borax Visitor Center
The mine's Borax Visitor Center, which includes a museum, historic mining artifacts, and a mine overlook, is open to the public.[6][7]
