  • (PDF) i) Direct Reduced Iron: Production

    Depleting resources of coking coal, the world over, is posing a threat to the conventional (blast furnace [BF]–basic oxygen furnace [BOF]) route of iron and steelmaking. During the last four decades, a new route of ironmaking has rapidly developed for direct reduction (DR) of iron ore to metallic iron by using noncoking coal/natural gas.

  • Iron and steel industry in the United States

    The traditional large integrated steel mill, which reduces metallic iron from ore (iron The specialty mills use iron and steel scrap, rather than iron ore, as feedstock, and melt the scrap in electric furnaces. Notable Specialty and Mini-Mills The two main inputs into iron- and steel-making are a source of iron and a source of energy.

  • Iron ore Wikipedia

    Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".

  • Metallurgist & Mineral Processing Engineer

    The more complicated the processes become, the more difficult it is to achieve and maintain stability. In mineral processing, unlike most processing operations, we have limited control of the main input, the feed ore. In most cases this inherently is variable and usually outside of the processors control.
