摘要
An acid treatment, in a liquid medium, of a solid containing a halophosphate and a rare earth compound is described. Further described, is the addition of a base to the medium obtained previously and separation of a solid phase from a liquid phase; mixing and calcination of the solid obtained previously with an alkaline solid compound; redispersing the calcined product in water, separation of the solid product from the suspension obtained in the preceding step; dispersing this solid in water and acidification of the dispersion and separation of the solid from this dispersion.
