Pig Iron: Meaning and Impurities Metals Industries

2021-7-4  Due to the reducing conditions in the furnace, the impurities in the ore get reduced and incorporated with iron. These impurities are mainly phosphorus, silicon, manganese, sulphur and carbon. The composition of slag, percentage of fuel and regulation of the blast furnace determine the quantities of phosphorus, sulphur, silicon, manganese and carbon.
