Recovery of High Purity Rare Earth Elements (REE) from ...
· Abstract. The goal of this project was to produce a high purity, separated (>90%) rare earth oxide (REO) product from coalbased sources. This product was achieved using the following three steps: Battelle's ADP: The ADP process involves pretreatment of ash (milling and caustic leaching), leaching of pretreated ash with nitric acid, roasting of loaded acid solution containing REE, and water ...
