The iron concentrate is melted in a reductive electric arc furnace to create pig iron and a saleable slag. The zinc rich fume undergoes a series of washing steps that eliminates impurities to create a zinc oxide of chemical quality (99.5% ZnO), a lead (+silver) concentrate and a brine effluent that meets marine discharge standards.

Iron Ore Pellets and Pelletization Process – IspatGuru

During the firing of these pellets, a glassy slag phase consisting of SiO2, CaO, and Fe2O3 of varying percentage is formed. Due to increased flux addition, there is formation of some slag and due to it, there is to a certain extent slag bonding with iron ore crystals. High basicity pellets have a basicity level greater than 0.6.
