Abstract
Unter einem Gesichtspunkt werden hierin Verfahren für die Aufbereitung von WC-Zusammensetzungen beschrieben. Ein Verfahren zum Aufbereiten einer WC-Zusammensetzung umfasst das lnkontaktbringen der WC-Zusammensetzung mit einer Elektrolytlösung, die ein kationisches Metalloxidationsmittel umfasst und das Oxidieren von einem oder mehreren Metallverunreinigungen der WC-Zusammensetzung mit dem kationischen Metalloxidationsmittel, um die eine oder mehreren Metallverunreinigungen in der Elektrolytlösung zu solubilisieren.
