The present invention relates to a method for recycling a waste abrasive material containing ceria, which effectively removes impurities from the waste abrasive material containing ceria and ensures the safety of a recycling process, thus enabling the suitable recycling of the waste abrasive material containing ceria. The method for recycling waste abrasive material containing ceria comprises: a step of dissolving the waste sludge containing ceria (CeO2) in a solvent solution comprising (a) a fluoride-based compound of NaHF2, (NH4)HF2 or KHF2, or (b) a mixture of sodium fluoride of NaF, (NH4)F or KF and non-hydrofluoric acid-based acid; a step of cleaning the waste sludge containing ceria to remove the impurities containing silica (SiO2) which were dissolved in the solvent solution; and a step of redispersing and filtering the cleaned waste sludge containing ceria, or drying and firing the cleaned waste sludge containing ceria.
