Borax operates California\'s largest open pit mine in Boron, California - one of the richest borate deposits on the planet. While boron is present everywhere in the environment, substantial deposits of borates are relatively rare. We supply nearly half the world\'s demand for refined borates, minerals essential to life and modern living.
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.
