About Mississippi Silicon
Mississippi Silicon operates a silicon metal production facility in Burnsville, Mississippi. The plant launched in late 2015, becoming the first new domestic silicon metal smelter built in the United States in four decades. The company is structured as a partnership between Rima Holding USA, Inc. (the majority owner, linked to Brazilian ferroalloy producer Rima Industrial S/A) and Clean Tech I LLC, a group of strategic investors and financial advisers. The facility produces raw silicon metal using submerged electric arc furnaces that reduce quartz or gravel (SiO₂) with a carbon source to yield 99% pure molten silicon, which is tapped in batches. Mississippi Silicon invested over $200 million in the Burnsville site and now supplies roughly 10% of the silicon metal consumed in the U.S. The operation emphasizes modern furnace controls, proprietary process techniques, and automated off-gas containment to achieve low-cost, high-quality output. The company sells silicon metal to customers that serve automotive, electronics, steel, and a broad range of consumer, industrial, and commercial markets across North America and globally. Automotive manufacturing is cited as a key end-use sector, alongside electronics and steel production. Mississippi Silicon was established to restore domestic silicon metal supply, leveraging low-cost Tennessee Valley Authority electricity, proximity to raw-material sources in Mississippi, Alabama, and Kentucky, and advanced automation to become one of the world’s lowest-cost and highest-quality producers. The venture also aims to create jobs in northeast Mississippi.
