Iron is extracted from hematite ( Fe 2 O 3) in a blast furnace. In a blast furnace, the ore is led into the top of the furnace along with coke and limestone and the limestone is decomposed into the hot furnace, forming calcium oxide. This reacts with the sandy impurities (silicon dioxide) to form a slag.

The purpose of a Blast Furnace is to reduce the concentrated ore chemically to its liquid metal state. A Blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore, coke, and limestone are dumped from the top, and a blast of hot air is blown into the bottom.

Combustion process. The iron in the processed ores must be dissolved out by chemical processes. This requires an element that binds oxygen more strongly than iron. This is exactly what carbon can do as a reducing agent. The carbon is fed to the blast furnace in the form of coke ( pyrolyzed coal) from the coking plant.
