Steelmaking: the basic oxygen process. Impurities in the iron from the Blast Furnace include carbon, sulphur, phosphorus and silicon. These have to be removed. Removal of sulphur. Sulphur has to be removed first in a separate process. Magnesium powder is blown through the molten iron and the sulphur reacts with it to form magnesium sulphide. This forms a slag on top of the iron and can be removed.
