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.
The steel story
The weight of many steel products will be reduced, losses will be minimised, and the already high recycling rate for steel will increase, resulting in more recycled steel to make new steel products. Pre-consumer recycling from the steelmaking and manufacturing processes will decrease due to increased process efficiencies and collaboration between steelmakers and their customers to reduce yield

AOD stands for argon oxygen decarburisation, a refining process associated with the production of stainless steel. Most stainless steel is initially produced in an electric arc furnace before being transferred to a separate ladle furnace for refining to achieve the precise metallurgical content required – a process known as secondary metallurgy or secondary refining.
