Iron Ore Mining | Techniques | Metal Extraction

The iron ore, coke and limestone are crushed into small round pieces and mixed and put on a hopper which controls the input. The most common ores of iron are hematite Fe 2 O 3, and magnetite, Fe 3 O 4. These ores can extract iron by heating them with the carbon present in the coke. Heating coal in the absence of air produces coke.

Blast furnace - Wikipedia

Blast furnaces operate on the principle of chemical reduction whereby carbon monoxide converts iron oxides to elemental iron. Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and reduce the iron oxide. The blast furnace operates as a countercurrent ...
