Hematite, also spelled as haematite, is a common iron oxide with a formula called Fe 2 O 3 and has been widespread in rocks and soils. It is mined as the main ore of iron.Varieties include kidney ore, martite (pseudomorphs after magnetite), iron rose and specularite (specular hematite).
Solution. Iron is extracted from its ore, haematite in a blast furnace. The ore is led into the top of the furnace along with coke and limestone. The limestone decomposes in the hot furnace, forming calcium oxide. This reacts with the sandy impurities (silicon dioxide) to form a slag.
This is the modern process for the manufacture of steel. For the manufacture of steel, 70-80% cast iron, 20-30% scrap iron and a little haematite is used. The charge is heated by passing producer gas (CO + N 2 in 1:2) and the process works on a regenerative system of heat economy. Oxidation is carried by haematite.
