Efforts to recover residues from the deep bath cell consisting of finely divided pure hafnium metal containing 2.5% oxygen, 0.29% nitrogen, and other impurities are described. A total of 5500 g was recovered representing about 65% recovery from the total anode material used. The recovered metal was then used as anode material in a 12-inch diameter cell to determine if a KCl + NaCl + K/sub 2/ZrF/sub 6/ electrolyte, containing 1.5% soluble zirconium, could be converted to a KCl + HaCl + K/sub 2/HfF/sub 6/ electrolyte by plating out the zirconium and replacing it with hafnium. The procedure was shown to be successful. Other aspects of procedure and earlier development are discussed. Progress in the electrorefining of yttrium is also reviewed and recommendations for further work are given. (J.R.D.)
