Extraction of Iron from Hematite
Ans. Iron is extracted from hematite through a process called reduction. In this process, the iron ore is heated with carbon in the form of coke (a type of coal) in a blast furnace. The carbon monoxide produced from the coke reduces the iron oxide in the hematite to iron metal.
