| titleOfInvention | A kind of technique that alkaline process handles monazite and extracting and separating rear earth |
| abstract | The present invention provides the techniques of a kind of alkaline process processing monazite and extracting and separating rear earth; concrete scheme is that alkaline process processing monazite is carried out under non-oxidizable protective atmosphere; obtain hydroxide containing trivalent rare earth; it directly carries out reacting the organic phase for obtaining supported rare earth with acidic extractant; trivalent cerium hydroxide has characteristic that is readily soluble and saving acid consumption relative to the hydroxide of quadrivalent cerium; rare earth is preferentially dissolved for subsequent faintly acid extractant, realizes and is created condition with the separation of the impurity such as indissoluble thorium dioxide；Trivalent rare earth hydroxide directlys adopt acidic extractant dissolution, is saponified the excessively high problem of mode rare-earth separating bring acid and alkali consumption using organic liquid alkaline or ammonium hydroxide, process simplifies. |
