<p><P>PROBLEM TO BE SOLVED: To provide a method of electrolytically processing lead, by which high purity lead is recovered even for a high Bi grade anode for electrolysis obtained by treating dust, in the recovery of Pb in the dry dust produced from nonferrous refining, a melting furnace for recycle raw material such as electronic components or a dry furnace for melt-treating industrial waste. <P>SOLUTION: The electrolytic method of lead includes: adjusting the high impurity anode having 5-30 mass% Bi grade so that antimony grade becomes 1-3 mass% and then, carrying out electrolytic process; and recovering the high purity lead. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
