  • Alternative emerging ironmaking technologies for energy

    Iron ore is chemically reduced to produce steel by one of these three process routes: blast furnace (BF)/basic oxygen furnace (BOF), smelting reduction, or direct reduction . Steel is also produced by direct melting of scrap in an electric arc furnace (EAF). Each of these processes are briefly explained in the section below.

  • Reduction of iron oxide in carbon monoxide atmosphere

    An experimental study on the kinetics of reduction of iron oxide in a fluidized bed reactor showed the existence of two stages of reduction. In the first stage, the rate of reduction was controlled by mass transport in the gas phase and in the second stage, the ratecontrolling mechanism was chemical reduction within small grains of the iron ore particles.
