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.Different Types of Iron Ore - 911metallurgist,01/12/2021· Usually steel-makers add limestone to iron ore to “flux” it, or draw out impurities during the smelting process.
