Abstract
Inventia se refera la un procedeu de purificare a electrolitului uzat, de la rafinarea cuprului prin precipitarea impuritatilor de As, Sb, Bi, Fe, Pb, Ag cu oxid cupric, separarea precipitatului hidrolitic, prin filtrare si spalare, respectiv obtinerea oxidului cupric din acelasi electrolit, prin precipitare cu hidroxid de sodiu în mediu alcalin si separarea sulfatului de sodiu din solutie prin cristalizare la rece.
