Rareearth occurrences in the Pea Ridge tailings

More than 70pct recovery of the rareearth values was achieved. Based on mineralogical characterization and prior analysis of rareearth bearing breccia pipe material at Pea Ridge, it is proposed that processing this phosphate concentrate on a vanner table would yield up to a 95pct recovery of the rare earths in the concentrate, with the apatite reporting to the tailings. Intensive ore ...
