| titleOfInvention | Process for the recovery of rare earths from rare earth-containing phosphors |
| abstract | Method for the recovery of rare earths from rare earth-containing phosphors with the following process steps: a) addition of solid ammonium chloride in a 1 to 2-fold mass ratio, based on the amount of chlorinatable metals, to the rare earth-containing phosphors, b) Chlorination of the chlorinable metals to metal chlorides in a rotary kiln or a sublimation plant at a temperature of 250 - 350 ° C in a period of 1 to 5 h c) adding an acidic solution to the metal chlorides to a pH of 1 to 4.5, wherein solid components are suspended in a solution, the metal chlorides going into solution, d) separation of the solid components from the solution, e) adding an acid to the separated solid components to a pH of less than 1, with solid components in suspension, f) separation of the solid components from the suspension, g) adding a precipitant to the separated solution and the separated liquid to precipitate a rare earth-containing precipitate, h) Separation of the rare earth-containing precipitate. |
