Hydrometallurgy Process on Radioactive and Rare Earth Elements Extraction from Monazite

Tin mining activities resulting tailing instead of tin metal.
Monazite, one of the tailing minerals, contains valuable and
strategic elements, such as Rare Earth Elements (REEs), uranium, and thorium. BATAN has developed the extraction methods for those elements. The process stages consist of milling, alkaline leaching, selective dissolution, and multistage precipitation. The products obtained were sodium tri-phosphate, REEs hydroxides, and uraniumthorium hydroxides concentrate. The process technology already brought to pilot scale with 50 kg monazite/batch of capacity.
