- Mini mills and integrated mills are two types of steel mills that differ in their production process, costs, and quality. Mini mills use electric arc furnaces (EAF) to melt scrap steel and produce steel products in smaller batches12. Integrated mills use blast furnaces to produce steel from iron ore and coke, and can produce larger quantities of higher-quality steel2. Mini mills have lower capital and energy costs, and a mostly nonunion workforce, while integrated mills have higher costs, and a highly unionized workforce2.Learn more:✕This summary was generated using AI based on multiple online sources.
