  • Extraction Of Iron From Its Ores Iron Dressing Reduction

    Steel is made primarily in a two step process. In the primary steelmaking step, liquid iron is converted into steel by the basic oxygen furnace (BOF) process, or by melting scrap steel or direct reduced iron (DRI) in an electric arc furnace. Secondary steelmaking is a refining process in which alloying metals are added and impurities are removed.Oct 10, 2017 Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities. The iron ore is dressed or crushed into 0.5 1 in. chunks, which increases surface area for reactions.
