    Abstract: The desulfurization agent for molten iron is made up of 70 to 95% commercial calcium carbide, 5 to 25% silicon dioxide, 0 to 10% of a metal oxide, and 0 to 5% calcium fluoride. The metal oxides are iron oxides and manganese oxides. The desulfurizing agent has been found to reduce the amount of calcium carbide in the resulting slag.

    Abstract: A method for dephosphorizing a manganese alloy by first desiliconizing the alloy to a level below 0.6%, and then dephosphorizing the low silicon alloy with barium carbonate or barium oxide in combination with an oxidizing agent. The lower the silicon content the better the results.

    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.
