The new production, expected to come online in 2015, will require new equipment at both the metallurgical and chemical sections of the plant, the company said in a release dated Feb. 10. The associated unit cost reductions, combined with a favorable energy outlook for (U.S.) manufacturing, should solidify our position as a sustainable, long-term, low-cost producer of magnesium," U.S. Magnesium president Ron Thayer said in a statement. The Salt Lake City-based magnesium producer said it completed an engineering study last year examining the possibility of boosting capacity to 90,000 tonnes per year to meet increased demand. That move came after the company boosted capacity at the Rowley plant in 2012 to 63,500 tonnes per year from 42,000 tonnes previously.
