Desulphurisation Slag is an iron slag derived from the desulphurisation skimming process. This material is an iron by- product that is encapsulated in varying levels of contaminants (S,Mg,Si), but has a stable chemistry with 75 -80% chemistry. The level of Fe% in the slag has been estimated by water displacement test.
