ABSTRACT:
A method for dephosphorizing a manganese containing melt is disclosed. The method encompasses the addition of a magnesium compound to a manganese containing melt to form magnesium phosphides which are removed from the melt. The method is carried out under pressure and the addition of a flux in the melt is employed to facilitate the removal of the phosphides from the melt.
