Iron Production
· Iron Production. The production of iron from its ore involves an oxidationreduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides. As a result of these impurities, iron ...
Iron Extraction by Blast Furnace Metallurgy
Iron, when extracted from iron ore such as haematite containing iron(III) oxide, Fe 2 O 3, in a blast furnace is called iron extraction blast furnace metallurgy. In this reduction reaction, oxygen is removed from the iron(III) oxide to leave behind iron. Generally, the extraction of metals and their isolation are based on three major procedures. The steps are: 1. Concentration of Ore 2 ...

Answered: Blast furnaces extract pure iron from. | bartleby
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: 2 C(s)+O,(g)→2 CO(g) In the second step, iron(III) oxide and carbon monoxide react to form iron and carbon dioxide: Fe,03(s)+3 CO(g)→2 Fe(s)+3 CO,(g) Write the net chemical equation for the production of iron from carbon, oxygen ...
