The proprietary process utilized by US Magnesium was originally developed by the National Lead Company in 1972. Throughout continuous operation, the facility has undergone several ownership changes: moving to Amax in 1980, MagCorp in 1989 and US Magnesium LLC in 2002.

In the past decade significant technological improvements have been made, converting the older facility to a truly state-of-the-art integrated magnesium and chemical production plant. Over $120 MM has been invested to develop and implement energy efficient electrolytic cells and gas capturing equipment, increasing magnesium production capacity by >30%, while reducing chlorine emissions by 99%, air emissions by 95%, and unit energy consumption by 25%. This combination led to the Company being awarded the prestigious Utah Manufacturing Environmental Consciousness Award in 2007.
