Iron ore is converted into various types of iron through several processes. and tools than any other known metal, its production was a closely guarded secret. region from which the iron ore was taken and the method used to extract the iron. . A byproduct of iron purification is slag,
Purification of the metal How is iron extracted from its ore? Its a long process which begins with Concentration through calcination roasting. Concentration removes the water and other volatile impurities such as sulphur and carbonates. This concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top.
Dec 11, 2021 The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small
