The amount of Orzan 805 required was from 5 to 7 lb/ton of ore (fig. 4). Rareearth recovery decreased significantly at greater than 8 lb of Orzan 805 per ton. Sodium fluoride additions of more than 6 lb/ton of ore yielded higher grade rareearth concentrates and a marked decrease in recovery (fig. 5).
