Roasting is the process in which a sulphide ore is strongly heated in the presence of air, converting the sulphide ore into its corresponding metal oxides. Thus, concentrated mercury (II) sulphide is roasted in air to form its corresponding oxide, i.e., mercury (II) oxide. Step 2-Conversion of mercury (II) oxide ore to mercury metal

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.
