How is iron extracted from haematite?

How is iron extracted from haematite? Medium Solution Verified by Toppr 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.

The Haematite reacts with Carbon in the cast iron to give pure iron and carbon monoxide gas which escapes. F e2O3+3C→ 2F e+3CO F e 2 O 3 + 3 C → 2 F e + 3 C O Limestone is then added as flux, and it creates the slag. Impurities such as S, Si pass into the slag and the slag later can be easily separated to yield pure iron.
