Extraction of Iron Metallurgy Blast Furnace and

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

Chapter 2. Production and Processing of Aluminum

1999-5-7  In Russia, due to a lack of bauxite, a process using nepheline as feed-stock has been used to produce alumina. Essentially the technique consists of sintering a nepheline ore, or concentrate, with limestone. The resultant sinter-cake consists of sodium and potassium aluminates and dicalcium silicate. This material is crushed, ground, and leached. After
