Auflösung des Bleis mit Hilfe von KupferfD-chlorld (CuCD-Mutterlauge. | IS | |
i ί |
In ein zylindrisches Reaktlonsgefaß führt man 21 einer 16.5 g/l KupfertD-lonen und 22.1 g/l Gesanukupl'er enthaltenden Lösung ein. Diese Lösung wird bei 80' C gehalten, und man führt aufeinanderfolgende Fraktionen von Bleikonzentrat In diese ein. Nach jeder Konzentrateinführung wartet man, blj die Konzentration an KupfertD-lonen stabilisiert 1st, bevor man zu einem neuen Zusatz von Erz übergeht. Man setzt dieses Verfahren bis zum gesamten Verschwinden der KupfertD-lonen fort. Die Ergebnisse sind In der folgenden Tabelle zusammengefaßt. |
