Technological Study on Yttrium-Cerium Phosphate Production by Phosphoric Acid Precipitation AITranslate
Abstract AITranslate
The technology is introduced for yttrium-cerium phosphate production with ReCl3 solution as the raw material and phosphoric acid as the precipitation agent. The influencing factors were investigated on the rare earth recovery and yttrium-cerium phosphate medium diameter, and the optimal technological con- ditions were determined. The results show that when the precipitation temperature is about 80 ℃ and the phosphoric acid concentration in the precipitated solution is about 0.12 mol/L, the rare earth recovery is higher. The yttrium-cerium phosphate product can be produced in a certain range of medium diameter, by controlling of single reactor output and appropriate stirring. By proper control of technological conditions, the yttrium-cerium phosphate product with a medium diameter of 3-10μm can be obtained in mass pro duction,and the rare earth recovery is over 90%.
