摘　　要：自然界中的稀土除了赋存在各种稀土矿中之外,还有一部分伴生在磷矿中,研究磷矿加工过程中综合回收稀土具有十分重要的意义。综述了磷酸分解伴生稀土磷矿以及从酸解液中提取稀土的研究现状,并结合磷酸法分解伴生稀土磷矿的优缺点,简要阐述了该方法的推广应用前景。Except for being exist in various rare earth ores in natme, some of the rare earth are associated with phosphate rock, it is of geeat significance to study the comprehensive recovery of rare earth during the processing of phosphate rock. The resealsh status of the phosphoric acid decomposition of phosphate rock associated with rare earth and the extraction of rare earth from the acidolysis solution is reviewed, combined with the advantages and disadvantages of the method of phosphoric acid decomposition of phosphate rock associated with rare earth, the prospects of promotion and application of the method are briefly described.
