A method of desulfurizing iron in an induction furnace is disclosed. High purity magnesium, carried in a lance controlled cartridge, is plunged into the lower zone of a molten metal pool of an induction furnace; the cartridge is held submerged for a period of 30-200 seconds. The molten metal column above the submerged cartridge must be at least 2.5 feet, preferably 6-7 feet. The molten metal temperature at the time of cartridge plunging is limited to 2400 DEG F. or less. Magnesium recovery will be at least 70%, which is better than other prior art methods by a factor of 1.4.
