What isiron ore?Ironores are rocks and minerals from which metallicironcan be extracted. There are four main types ofiron oredeposit: massivehematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone.

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 arehematite 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.
