A process method for recovering rare earth from ionic type rare earth low-concentration leachate adopts HD325 ion exchange resin R-N+(CH3)3OH as an absorbing material and performs absorption-desorption treatment on the ionic absorption type rare earth low-concentration leachate to recover the rare earth from the rare earth low-concentration leachate. The process method comprises the specific steps of using 1kg parts by weight of low-concentration leachate as a main raw materials, using hydrochloric acid or sulfuric acid to adjust leachate pH to be 4.5-5.5, using HD325 ion exchange resin 2.2-2.8g to perform dynamic absorption processing on the rare earth; controlling the flowing speed of the leachate to be 10 ML/min during absorption processing, wherein the dynamic absorption contact time of the leachate and the HD325 ion exchange resin is 4-8 minutes; then using percentage by weight of hydrochloric acid with concentrating ranging from 5% to 7% to perform desorption on absorbed rare earth at the flowing speed ranging from 6mL/min to 8mL/min for 100-145 minutes and recovering the rare earth. Absorption and desorption recovery can be effectively performed on the low-concentration leachate by means of the process method, a process working procedure is short, dosage amount is small, load on a follow-up treatment process is small, and production cost is low.
