Iron Ore Reduction an overview ScienceDirect Topics

Currently the dominating process for the iron-ore reduction is the blast furnace (BF) technology. These furnaces consist of a moving bed reactor with a counter-current flow of the solid reactants against a reducing gas. Not only are the energy costs relatively high for these blast furnaces the pollution problems can also be quite severe.
