Reduction.<\/p>\n<p>Iron ore is a mineral that contains iron. It is the primary raw material used to make iron and steel. Iron ore is mined from the earth and then processed to remove impurities. The most common type of iron ore is hematite, which is a red ore.<\/p>\n<p>The manufacturing of iron from iron ore involves the process of reduction. Reduction is a chemical reaction in which an element or compound loses oxygen. In the case of iron ore, the iron is reduced from its oxide form to its metallic form.
