A method of fluidizing a cold lime-silica slag covering a molten metal. An acid flux is prepared from a particulate admixture of sodium fluoroaluminate and sodium silicate. The flux is mixed with the cold slag forming a fluid slag having at least 1% by weight F- and at least 1% by weight Na. sub. 2 O. The treated slag has a reduced melting point allowing it to be mechanically skimmed from the molten metal and has a high sulfur capacity.
