The extraction of iron from its ore is the third and the penultimate process in metallurgy, which is the process of separating metals from their ores. The common ores of iron are iron oxides. These oxides can be reduced to iron by heating them with carbon in the form of coke. Heating coal in the absence of air produces coke.

Ore Processing. Once an ore has been mined, it must be processed to extract pure metal. All ore minerals are mixed with less desirable components called process of physically separating gangue minerals from orebearing minerals is called ore is processed (typically very close to the mine), it is ground to a fine powder and the ore minerals are physically separated ...

Iron ore, solid carbon, and limestone are warmed to very high temperatures in an oven during the process of extracting pure iron. Afterwards, the oven contains pure iron and a waste product called slag. The total mass of the iron and slag is less than the total mass of the iron ore, solid carbon, and limestone. What happened to the remaining mass?

The production of iron from its ore involves an oxidationreduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides. As a result of these impurities, iron must be first ...
