Figure 1: Principle of the Steam-Iron process. In the reduction step, the iron oxide is treated with a reducing feedstock (such as hydrogen, mixtures of hydrogen and CO, and various other fuels), and as a result of the reaction, the metal (iron) or a partially reduced oxide is obtained. The second step consists in the

Blast furnaces extra 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)+O_(2)(g)→2CO(g) In the second step, iron(III) oxide and carbon monoxide react to form iron and carbon dioxide: Fe_(2)O_(3)(s)+3CO(g)→2Fe(s)+3CO_(2)(g) Suppose the yield of the first step is 84.% and …

In the first step of the process, iron oxide is reduced from hematite (Fe 2 O 3) ... wustite or metallic iron has been formed, the reducing gas is switched to steam. In the second step of the process, hydrogen is produced by oxidizing the metallic iron or iron oxide with steam. Fig. 2 shows a basic scheme of the Steam-Iron process.

The technology created two major developments in iron production. First, blast furnaces were now able to make cast iron for the production of hollowware such as pots and kettles. Second, in the new "indirect process" cast iron could be converted into wrought iron with a higher yield of iron from the ore than the direct process.

The second is to make wrought iron or steel from pig iron by puddling a further process. Commercially available iron is classified based on purity and the abundance of additives. ... Pig iron is not a salable product, but is an intermediate step in the production of wrought iron, steel and cast iron from iron ore. Wrought Iron was created from ...
