As the blast passes through the burning fuel it takes from the oxide of iron its oxygen, passing out as carbonic oxide, and thus compels it to yield up the whole of the metal iron. The iron, as it melts in the furnace, combines with the carbon of the fuel, and becomes cast iron.
Iron is extracted from its oxide ore called HAEMATITE (Fe2O3).

Extraction of iron from its oxide - definition Oxides ores of iron after concentration through calcination/roasting are mixed with limestone and coke and fed into a blast furnace from its top. Here, the oxide reduced to its metal. Smelting method used in the extraction of iron - definition Extraction of iron from its oxides Oxide ores of iron, after concentration through calcination/roasting (to remove water, to decompose carbonates and to oxidise sulphides) are mixed with limestone and coke and fed into a Blast furnace from its top. Here, the oxide is reduced to the metal.

Removal of Volatile Impurities by Roasting and Calcination H 2 O → H 2 O (g)↑
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.
Iron is extracted from its oxide. ore called HAEMATITE (Fe2O3).The process of the extraction of iron is carried out by the following steps: Concentration of ore Calcination or Roasting of ore Reduction of ore.
Extraction of Iron from oxide Oxide ores of iron, after concentration through calcination/roasting (to remove water, to decompose carbonates and to oxidise sulphides) are mixed with limestone and coke and fed into a Blast furnace from its top. In this case, the oxide is reduced to the metal. One of the main reduction steps in this process is:
