Summary

Milligram and microgram quantities of rhodium were successfully recovered from a simulated oxide ore by fire assay collection in copper. Rhodium was isolated by cation-exchange techniques and determined by standard methods. Acceptable recovery was also obtained from a sulphidic sample containing iron and nickel. Losses to siliceous residue, slag, pot wall, and ion-exchange resin were found to be negligible.

Zusammenfassung

Durch Schmelzanreicherung in Kupfer konnte Rhodium in Milligrammund Mikrogramm-Mengen erfolgreich aus einem künstlich hergestellten oxydischen Erz zurückgewonnen werden. Es wurde durch Kationen-Austauschverfahren abgetrennt und nach den Standardmethoden bestimmt. Auch bei einer eisen- und nickelhaltigen sulfidischen Probe konnte eine zufriedenstellende Wiedergewinnung erzielt werden. Die durch kieselsÄurehaltigen Rückstand, Schlacke, GefÄ\wandablagerungen und Ionenaustauscher verursachten Verluste waren geringfügig.
