摘要

An industrial process for refining non-ferrous metals or their alloys starting from an aqueous solution with or without electrolysis, especially allowing the elimination of lead from cuprous alloys and characterized by: A) preparation of an aqueous solution starting from a salt or a mixture of several mineral or organic salts having either the metal base or the metals to be fine-tuned to different metals. B) addition of mineral or organic acids to the aforementioned solution whose nature is determined by the property possessed to a greater or lesser degree by the impurities combined with the metal coming into solution in the baths used. C) arrangement of the metals to be treated and the dissolution inside a stirrer. D) electrolysis of the whole to activate the reactions. E) combination and cooperation of the abovementioned agents to obtain an industrial process for refining non-ferrous metals or their alloys starting from an aqueous solution with or without electrolysis that allows especially the elimination of cuprous alloys.
