Our History

Tronox’ Henderson operation has been a business landmark in Southern Nevada for many decades, as a descendant of the World War II U.S. government-built magnesium manufacturing plant. After the war, six of the original ten production unit buildings and surrounding property were purchased from the government by Western Electro-Chemical Company (WECCO).

WECCO was purchased in 1954 by American Potash, who continued to operate the site until it was acquired by Kerr-McGee in 1967. In 2005, Kerr-McGee spun off the chemical division and renamed it Tronox LLC. In 2012, Tronox LLC combined its titanium dioxide (TiO2) pigment and Electrolytic and Specialty Chemicals with Exxaro Mineral Sands to form Tronox Limied. The Electrolytic Products of Tronox Limited remains dedicated to the production of energy driven chemicals.

Since 1948, the Henderson operation has produced a variety of specialty chemicals including chlorates and perchlorates, manganese dioxide, elemental boron, boron trichloride, boron tribromide and boranes. While some compounds have had more down-to-earth uses such as manufacturing paper products, sports equipment and pharmaceuticals, others were intended for aircrafts, rockets and the space shuttle.

Today, the Henderson site employs nearly 100 full-time workers, under the leadership of an experienced maintenance team and senior staff, each with over 15 years of work history. Our dedicated workforce has a long history of charitable efforts and community involvement.

Electrolytic Products of Tronox has grown to be a foremost producer of electrolytic manganese dioxide (EMD), which is the active ingredient in primary batteries and a feedstock for LMO batteries. We have also become a leading global producer of boron trichloride (BCI3), used in the manufacture of semiconductors, LED and LCD screens, epoxy resin, pharmaceuticals and boron fibers. Other products include boron and lithium manganese oxide (LMO) feedstock.

We value this solid operating platform, which has a long history of operational best practices and production methods. The ISO-certified Electrolytic Products of Tronox continues to yield improvements and foster differentiation and superior customer service in a competitive market.
