Iron ore is used to make iron and steel and iron is produced in a blast furnace by reducing iron oxides with carbon and it is the carbon that removes the oxygen from the iron oxides – the.Mar 26, 2020 Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
We will discuss the extraction of iron from iron ore as an example. Extraction of iron. Iron atoms are found in the compounds FeO, Fe 2 O 3 and Fe 3 O 4 and in rocks like haematite and magnetite. South Africa is the seventh largest producer of iron ore in the world. Iron has been mined in South Africa for thousands of years.May 10, 2021 Top five largest iron ore producing companies in the world in 2020. 1. Vale – 300 million tonnes.
