The invention discloses a method for industrialized production of high-purity neodymium oxide. The method comprises the following steps that 1, enrichment material liquid containing lanthanum, cerium, praseodymium and neodymium is mixed with an organic phase, extraction is performed through a lanthanum-praseodymium-cerium/praseodymium-neodymium fuzzy extraction module, an outlet water phase of the fuzzy extraction module contains lanthanum, cerium and praseodymium, and the outlet organic phase washed with washing liquid contains praseodymium and neodymium; 2, the praseodymium and neodymium of the organic material liquid containing praseodymium and neodymium obtained in the step 1 are separated through a praseodymium/neodymium separating module, an outlet water phase of the praseodymium/neodymium separating module is an enriched product of praseodymium and serves as the washing liquid used for the lanthanum-praseodymium-cerium/praseodymium-neodymium fuzzy extraction module in the step 1, the outlet water phase of the praseodymium/neodymium separating module contains high-purity neodymium, and the purity is 99.99%-99.999%; 3, the neodymium containing material liquid inn the step 2 is subjected to precipitation, calcinations and packaging to obtain a high-purity neodymium oxide produce. The method has the advantages of being low in production cost, high in product purity and capable of performing large-scale continuous production.
