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.

Magnetite ore and processing. A general processing circuit for magnetite ore is initial crushing and screening of run of mine (ROM) ore to <6 mm. The ore is then milled to a specified grind size to liberate the iron minerals from the gangue, then processed further to produce a magnetite concentrate, commonly by a wet magnetic separation process.
