Calcination, Digestion, Monazite, Rare earth oxide, Selective precipitation.Abstract
The present study investigates to support the production of rare earth oxide, which has been used for next research work of individual rare earth elements purification process from monazite, Mongmit Myitsone Region. The processing of rare earth oxide in this study involves four main parts, digestion of monazite concentrate, selective precipitation of rare earth hydroxide, precipitation of rare earth oxalate and calcination of rare earth oxide. The chemicals used in this study were commercial grade from local market. The products from each processing process were characterized by XRD and XRF. The final product contained (> 95 %) of total rare earth oxide and fulfilled to apply next purification process. This paper review the cheaper and easily way to extract rare earth oxide from Myanmar monazite.
