The ferroalloys plant was built in the 1930’s and began production on site in 1934 by Union Carbide. At its origin it produced most ferroalloys, but in the 1980’s began to focus on ferrosilicon and silicon metal. Silicon Metal has been the main product since 1990 with production through carbothermal reduction. Plant was formerly operated by Union Carbide until 1981, by Elkem from 1981 until 2005, and by Globe since 2005. The plant is currently operated as a joint venture with Globe and Dow Corning.
