Concentration of ores: Removal of impurities, such as soil, sand, stone, silicates, etc. from mined ore is known as Concentration of Ores. Ores which are mined often contain many impurities. These impurities are called gangue. First of all, concentration is done to remove impurities from ores.
Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slagforming agents and solid fuel (coke).
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 sulfur and carbonates.
