• Description:
  The Bureau of Mines investigated methods for beneficiating platinum- group metal ores from the Stillwater Complex, Montana, as part of its program to increase the supply of critical and strategic minerals and metals from domestic resources. This report presents results of a 5-day continuous campaign employing a pilot flotation mill to recover sulfide concentrate containing platinum-palladium values from anorthositic ore. A mercaptobenzothiazole-sulfuric acid reagent suite was used. The pilot flotation mill was operated at an average feed rate of 106 lb/hr of ore. A rougher concentrate containing 8.5 pct of the feed was prepared; it assayed 1.1 Oz/ton pt and 3.5 Oz/ton pd. Recovery of platinum and palladium were 91 and 87 pct, respectively.
