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.

Iron ore BHP

Iron ore BHP

Iron ore is mixed with coke (from super-heated metallurgical coal) in a blast furnace. Air that has been heated to around 1,200 degrees Celsius is injected into the furnace, creating a flame temperature of 2,000 degrees. This converts the iron ore to molten pig iron and slag. Then, impurities are removed and alloying elements are added.

May 21, 2020 The blast furnace route of iron making is predominant in India. Blast furnace (BF) process of iron making is a process where liquid iron (hot metal) and liquid slag are produced by the reduction of iron-bearing materials (sinter and/or pellet and lump ore) with coke and by fluxing of the gangue material of the feed materials (IBM 2011). The process is the result of a series of chemical reactions which take place in the blast furnace.
