Manganese - iron, sulphur, cast and carbon

Manganese unites with the sulphur and forms a manganese sulphide at a temperature above the solidifying temperature of cast iron. Con sequently this manganese sulphide has no more detrimental effect on the iron than so many small particles of any neutral impurity, and eventually reaches the slag, unless ferrous oxide is present.
