PROCESS FOR THE SEPARATION OF INDIUM FROM ACIDIC SOLUTIONS CONTAINING IT

摘要

"PROCESS FOR THE SEPARATION OF INDIUM FROM ACIDIC SOLV TIONS CONTAINING IT" The invention relates to the separation of indium from acidic solutions containing it, by means of the formation of complex compounds with complexing substances supported on either planar or tubular membranes, of polymer ic character, and of the de-complexing of the same, followed by a re-extraction or stripping with acidic solutions, which may be either of the same type of, or different from the starting solutions.
