This concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. 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
Oct 02, 2014 · Pig Iron. Pig iron is the basic material from which, wrought iron and steels are produced. It is obtained by smelting (chemical reduction) of iron ore in the blast furnace. In addition to iron, Pig iron contains varying quantities of other elements such as carbon,
In 2010, world iron ore pellet production was 388 Mt. It could be argued that the current pellet production process has been enabled by the use of binders – practical experience has shown that it would be nearly impossible to agglomerate iron ore using rotary drums and discs without using a binder.
Aug 10, 2011 · Blast furnaces extract pure iron from the iron (III) oxide in iron ore in a two step sequence. In the first step, carbon and oxygen react to form carbon monoxide: 2C (s) + O2 (g) > 2CO (g) In the second step, iron (III) oxide and carbon monoxide react to form iron and carbon dioxide: Fe2O3 (s) + 3CO (g) > 2Fe (s) + 3CO2 (g) Write the net chemical equation for the production of iron from

Bauxite is the main source of the rare metal gallium. During the processing of bauxite to alumina in the Bayer process, gallium accumulates in the sodium hydroxide liquor. From this it can be extracted by a variety of methods. The most recent is the use of ionexchange resin.
Mar 16, 2013 · DR process, DRI, HBI, Iron making. Metallization, reformed natural gas, residual elements, Rotary kiln, Direct reduced iron (DRI) is technically defined as iron ore which has been reduced to metal without melting it. Hot briquetted iron (HBI) is a densified form of DRI to facilitate its handling and transport. History
Iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned. Included in this article also is a discussion of the mining of iron and of its preparation for smelting. Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive.
