Abstract:

Cerium oxide is to be recovered from monazite, which contains about 27.35% CeO2. The principal objective of this study is to be able to extract cerium oxide from monazite of Moemeik Myitsone Area. The treatment of monazite in this study involves three main steps; extraction of cerium hydroxide from monazite, solvent extraction of cerium hydroxide, and precipitation with oxalic acid and calcination of cerium oxalate.
