Extraction of Iron Metallurgy Blast Furnace and Reactions

Extraction of Iron Metallurgy Blast Furnace and Reactions

How is iron extracted from its ore? It’s 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. It is in the blast furnace that extraction of iron occurs.

Jan 01, 2010 The blast furnace process is primarily used in the carbothermic reduction of oxides, such as iron, zinc, and lead. Most of the iron ore bodies commercially explored consist of iron oxides. Consequently, rich iron ore and/or iron oxide pellets formed from concentrate can be added directly to a blast furnace (see Iron Production).
