A process for upgrading low-grade magnetite-containing iron ore with minimum fine grinding. The dry ore is first comminuted to between about three-fourths inch and 10 mesh particle size and magnetically separated. The dry tailing is discarded and the concentrate is ground to between about 20 and 100 mesh and again subjected to dry magnetic separation.

Iron Ore Mining | Techniques | Metal Extraction

Haematite and magnetite are the most commonly found iron ore minerals. The smelting process allows the iron ore to be heated with carbon. The carbon combines with the oxygen and carries it away, leaving behind iron. Blast furnaces are so hot which is why they melt the iron, and drain it off to be poured into moulds to form bars, called ingots.
