It may be an integrated steel works carrying out all steps of steelmaking from smelting iron ore to rolled product, but may also be a plant where steel semi-finished casting products are made from molten pig iron or from scrap. What Is a Steel Mini Mill? | Career Trend,A steel mini mill is a facility which produces steel products from recycled scrap metal. Unlike integrated steel mills, which make new steel from iron ore in a blast furnace, mini mills melt and refine scrap steel using electric arc furnace (EAF) technology. According to a U.S. Environmental Protection Agency (EPA) report, while mini mills accounted for 10 percent of U.S. steel production in 1970, by 2006, over half of the national steel output was produced in mini mills.iron ore mini mill - sebastiaanenilse,iron ore mini mill.
