The invention discloses a method for decomposing rare earth concentrates, in particular to a method for decomposing rare earth concentrates by reverse leaching. The process steps include: filtration, drying, roasting and magnetic separation. The utility model is characterized in that: first, reverse leaching and impurity removal, the water-soluble substance is first dissolved by dilute hydrochloric acid, and the rare earth element is left in the leaching residue; then the leaching residue is filtered and dried, and then oxidized and roasting is performed; Rare earth minerals are selected under the magnetic field strength. The object of the present invention is to provide a rare earth concentrate decomposition method with low raw material consumption, low production cost and high rare earth recovery rate.
