Abstract
The present invention provides a method for recovering phosphorus and rare earth from rare earth-containing phosphorite and a substance containing rare earth phosphate. The method includes the following steps: step S1, leaching the rare earth-containing phosphorite by using a phosphoric acid-containing solution to obtain an acid leaching slag and a leaching solution; step S2, aging the leaching solution to obtain a rare earth phosphate precipitate; the reaction temperature of the step S2 is higher than the reaction temperature of the step S1. The rare earth-containing phosphorite is acid leached by using a phosphoric acid-containing solution at a relatively low reaction temperature, and then the leaching solution is subjected to an aging treatment at a relatively high temperature, such that the rare earth ions form a rare earth phosphate precipitate, thereby achieving the efficient separation and recovery of the rare earth and phosphorus.
