The invention discloses a method for enriching and recovering rare earth from phosphorite, which drives a large quantity of rare earth elements to be enriched into a phosphate system and be separated and recovered by inhibiting loss of the rare earth in phosphogypsum through optimizing the technological conditions and adding a calcium sulphate crystal seed and/or an active additive on the premiseof not changing the wet-method phosphate process. Compared with the prior art, the method controls proper technological conditions and particularly adds the calcium sulphate crystal seed and/or the active additive, can improve the crystalline morphology of the phosphogypsum, reduce the eutectic effect and the adsorption effect of phosphate rare earth and calcium sulphate, reduce enrichment of thephosphate rare earth and the calcium sulphate to the phosphogypsum, make the enrichment ratio of the rare earth in phosphate reach more than 80 percent, and be favorable for recovering the rare earthfrom the phosphate. Moreover, the method can meet the requirements of wet-method phosphate production, has simple technique and high content of rare earth in the phosphate, and can adopt proper technology to recover rare earth from the phosphate and realize effective combination of rare earth recovery technology and phosphorization technology.
