• Description:
  "The Bureau of Mines investigated methods for beneficiating platinum- palladium ores from the Stillwater Complex, Montana. Results of bench- scale and pilot-scale studies employing froth flotation to recover sulfide concentrates containing platinum-palladium values from a serpentinized ore are presented. Best results in the pilot mill were obtained with a sodium isobutyl xanthate-normal dodecyl mercaptan collector combination at a natural ph of 8.2. A rougher concentrate containing 1.7 Oz/ton pt and 4.7 Oz/ton pd was prepared. Recoveries of platinum and palladium were 96 pct and 86 pct, respectively. Batch cleaner flotation of rougher concentrates yielded concentrates containing 3.7 Oz/ton pt and 9.8 Oz/ton pd." - NIOSHTIC-2
