2007-10-31 A simple and safe class demonstration of the reduction of iron ores (Fe 2 O 3, Fe 3 O 4) to iron involves burning a match until the end is charcoalised, dipping the burnt end into water and then into some iron oxide.

2010-1-1 Gas phase extraction was shown to result in reasonable extractions in short periods of time, with iron extraction above 80% after 4 h for the low metal oxide concentration charge. The process was shown to depend on all the mentioned variables, and there is need to find a relationship which will be able to predict how extraction proceeds with time.

It is in the blast furnace that extraction of iron occurs. The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag. What happens in the Blast Furnace? The purpose of a Blast Furnace is to reduce the concentrated ore

Iron(III) oxide + carbon → iron + carbon dioxide. 2Fe 2 O 3 (s) + 3C(s) → 4Fe(s) + 3CO 2 (g) Carbon is more reactive than iron. The iron oxide is reduced by the carbon (the oxygen is removed) to form metallic iron. The sodium carbonate fuses easily and brings the iron oxide into close contact with the carbon.

2018-1-1 Carbonated red mud concentrated with magnetic separation followed by muffle furnace roasting using suitable reductant produced a 50.5% iron-rich concentrate with 70% iron recovery. This technique of iron recovery from red-mud consumes two harmful industrial wastes and shows promising results. © 2018 Elsevier Ltd.

ii) By passing of steam over red hot iron: This prevents rusting of iron due to the formation of a thin layer of ferrosoferric oxide (Fe 3 O 4) on the surface of the iron. iii) By metallic coating. By coating iron surface with metals such as zinc, tin, aluminium, etc. iron is prevented from rusting in two ways:
