Steelmaking and Refining | Introduction to Chemistry

Modern steelmaking processes are broken into two categories: primary and secondary steelmaking. Primary steelmaking uses mostly new iron as the feedstock, usually from a blast furnace. Secondary steelmaking is performed in an electric arc furnace and uses scrap steel as the primary raw material. Refining consists of purifying an impure metal.
