ANODE REGENERATION PROCESS

PROBLEM TO BE SOLVED: To regenerate an anode of high purity.SOLUTION: An anode after used, molten indium, in which indium 99.995%is molten in a quantity corresponding to a reduction consumed by electrolysis, and from which a gas component is removed, and a solid chloride agent of 1 mass % or more an...

Zusammenfassung:	PROBLEM TO BE SOLVED: To regenerate an anode of high purity.SOLUTION: An anode after used, molten indium, in which indium 99.995%is molten in a quantity corresponding to a reduction consumed by electrolysis, and from which a gas component is removed, and a solid chloride agent of 1 mass % or more and 3 mass % or less with respect to the anode quantity after use, and a solid chloride to eliminate an impurity from the molten indium. The molten indium having an impurity removed is poured into a mold thereby to cast an anode of a purity of 99.995% having the gas component removed.SELECTED DRAWING: Figure 1 【課題】高純度の陽極を再生する。【解決手段】使用後の陽極、及び電解により消費した減量分に相当する量の、ガス成分を除いた純度９９．９９５％以上のインジウムが溶解した溶融インジウムと、使用後の陽極量に対して１質量％以上、３質量％以下の固体塩化剤とを混合して、溶融インジウムから不純物を除去し、不純物を除去した溶融インジウムを型に流し込み、ガス成分を除いた純度９９．９９５％以上の陽極を鋳造する。【選択図】図１
