Extraction of Iron from Hematite. 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.
