The invention relates to a flotation method for mineral type rare earth ore, and belongs to the technical field of comprehensive utilization of mineral resources. The method comprises the following steps: carrying out ore grinding dissociation on the mineral type rare earth ore to obtain an ore grinding product; the ore grinding product is subjected to flotation, and rare earth concentrate is obtained; wherein the flotation is non-transmission flotation, and a non-transmission flotation tank is adopted in the flotation; the non-transmission flotation tank has the advantages of multi-stage efficient mineralization, non-blocking jet mineralization, tailing-middling sedimentation type separation and the like, microbubble flotation can be achieved, the enrichment ratio and the separation efficiency are high, and the purpose of improving the grade and the recovery rate of mineral type rare earth flotation concentrate REO is achieved through the single flotation technology with the non-transmission flotation tank a
