The key raw materials in steelmaking include iron ore, coal, limestone, and recycled steel . Actual steel is mostly iron ore and less than 2% carbon, the other materials are used in the manufacturing of crude steel. Iron ore is mined in about 50 countries . Nearly all of the iron ore that is mined, specifically about 98%, is used to produce steel. 5% of the Earths crust is made up of iron oxides, or ores, and iron is 100% recyclable and ...

Extracting iron from iron ore . In the 12th century, men started to mine iron ore from rock. They learnt how to recognize rock that contained iron ore and broke off pieces of rock by lighting fires against it, to make it brittle. The work was done from the surface down, excavating the rock in opencast mines and following the veins of ore.
How do we make iron, steel, other alloys, aluminium, sodium, copper, zinc, titanium and chromium. The six linked pages include an introduction to metal extraction or metal manufacture and production. There are detailed notes on the extraction of iron and its conversion to steel. The extraction and manufacture of aluminium and sodium are described.
Iron ore is used to make iron and steel eg haematite and magnetite. Iron is produced in a blast furnace by reducing iron oxides with carbon and it is the carbon that removes the oxygen from the iron oxides the carbon is known as the reducing agent .
