4. Manganese: The quantity of manganese varies from 0.2 to 1.5%. The source of this impurity in iron is from the ore. Manganese dioxide in ore is reduced at higher temperature as the reduction reaction is endothermic in nature. Manganese thus formed gets mixed up with iron. Some of the manganese is removed by acid slag.
