In the present chapter, the most innovative trends in electrolysis of iron ore such as electrowinning and molten oxide electrolysis are described. Since electrolysis produces no CO 2, it could theoretically be zero-carbon, but only if the electricity needed to power, the process is produced without generating CO 2 emissions.

Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then 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.
