Learn about Borax

Borax traces its roots to California's Death Valley, where borate deposits were discovered in 1872. The twenty mule teams Borax used to haul ore out of the remote desert live on as a symbol of the company's commitment to innovation. The current open pit in the Mojave Desert began as an underground mine in 1927, and Boron Operations was converted to a surface mine in the late 1950s. At this time extensive facilities for refining ore were built. In 1980, Borax built its boric acid plant, securing the company's position as the world's leading boric acid supplier.
