monazite processing

Mineral Sands: NORM Appendix - World Nuclear Association

Monazite and xenotime may be processed to recover rare earth oxides a, which are used in electronics and other specialist fields, but the presence of thorium b makes them commercially unattractive. Between 1980 and 1995 some 160,000 tonnes of monazite was sourced from mineral sand mining in Western Australia and exported to France for processing to recover rare earth minerals, but the .
