US Borax

U.S. Borax, part of Rio Tinto, is a global leader in the supply and science of borates—naturally occurring minerals containing boron and other elements. From the very beginning, we have been at the forefront of borate technology, research, and development. We supply 30% of the world’s need for refined borates from our world-class mine in Boron, California, about 100 miles northeast of Los Angeles. Our customers rely on boron and borates to create an extraordinarily diverse range of products essential to life and to modern living.
