ABSTRACT DESULPHURISATION OF FERROUS MELTS Method of desulphurising a ferrous melt comprises injecting into the melt lime-containing particles having smooth surfaces, a low tendency to absorb moisture and blocked pores formed by solidification of molten inorganic matter in the pores of the lime. Method of making a desulphurisation agent for the desulphurising method comprises calcining limestone with, for example, sodium carbonate, calcium fluoride or siliceous matter.
