The invention discloses a recovery method for uranium. The recovery method disclosed by the invention comprises the following steps of: 1) performing fractional extraction to obtain an organic phase containing uranium by taking an acidic aqueous solution containing thorium and uranium, an organic solvent containing methyl diheptyl (1-methyl) phosphonate as an extraction agent and an acidic aqueous solution as a washing liquid, wherein the volume concentration of the methyl diheptyl (1-methyl) phosphonate in the extraction agent is 1-6%; and 2) counter-extracting the organic phase containing uranium obtained in the step 1) by way of multistage countercurrent. According to the recovery method disclosed by the invention, the recovery rate of uranium is relatively high, the extraction stages are few, and the efficiency is relatively high.
