Reduction.<\/p>\n<p>Iron ore is a mineral that contains iron. It is the primary raw material used to make iron and steel. The iron ore is mined and then crushed into a fine powder. The powder is then mixed with coke and limestone and heated in a blast furnace.

The carbon monoxide then reacts with the iron ore, reducing it to iron. The iron is then melted and poured into molds to form ingots.<\/p>\n<p>Oxidation is a chemical reaction in which an element or compound loses electrons. In the case of iron ore, the iron is oxidized when it reacts with oxygen in the air. This reaction produces iron oxide, which is a solid.<\/p>\n<p>Fractional distillation is a process used to separate liquids with different boiling points. The liquids are heated and then allowed to vaporize. The vapor is then condensed and collected. The liquid with the lowest boiling point will vaporize first and be collected first. The liquid with the highest boiling point will vaporize last and be collected last.<\/p>\n<p>Electrolysis is a process that uses electricity to separate compounds.
