Demo makes way for new opportunities
Many people think that mine closure work comes at the end of a mine’s life—when operations end. But, sometimes mines need to close parts of a site during its operating life.

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. We are 1,000 people serving 650 customers with more than 1,800 delivery locations globally. We supply around 30% of the world’s need for refined borates from our world-class mine in Boron, California, about 100 miles northeast of Los Angeles.  Learn more about Rio Tinto.
