METHOD FOR SEPARATING THE CERE FROM MIXTURES OF RARE-DDPHOSPHATES |
| abstract |
The invention relates to a process for the separation of cerium from rare earth concentrates incurred in the partial neutralization of nitric acid Rohphosphataufschlussloesungen. The object and object of the invention is to separate the cerium from the rare earth phosphates in an early stage of the work-up process without prior removal of impurities contained in the starting material. According to the invention, the rare earth phosphates are treated with an excess of concentrated nitric acid, whereby the Ce3 contained in the solution is oxidized to Ce4 and subsequently precipitated by blunting with alkalis of cerium (IV) phosphate. |
