Beneficiation of Iron Ores – IspatGuru
03/04/2014 · Beneficiation of Iron Ores. Iron ore is a mineral which is used after extraction and processing for the production of iron and steel. The main ores of iron usually contain Fe2O3 (70 % iron, hematite) or Fe3O4 (72 % iron. magnetite). Ores are normally associated with unwanted gangue material. Grade of iron ore is usually determined by the total ...

Nowadays, over 93% of the total iron production from ores is taking place via BF route. An alternative route for iron production is direct reduction, which is described more thoroughly in a separate chapter. Figure illustrates the position of the blast furnace as well as direct reduction in the overall steelmaking process [8].

Metals | Free FullText | Hydrogen Ironmaking: How It Works
03/06/2020 · A new route for making steel from iron ore based on the use of hydrogen to reduce iron oxides is presented, detailed and analyzed. The main advantage of this steelmaking route is the dramatic reduction (90% off) in CO2 emissions compared to those of the current standard blastfurnace route. The first process of the route is the production of hydrogen by water .

How is Iron Extracted from Iron Ore |
C + O2 → CO2. The heat produced by this reaction is the main source of heat in the blast furnace that is used for iron production. At the bottom of the furnace, the temperature is very high, which causes more of the coke to react with carbon dioxide, producing carbon monoxide. C + CO2 → 2CO. The carbon monoxide then becomes the "reducing ...
