$^{244}$ Cm was separated and recovered as an oxalate from $^{244}$ Cm- $^{240}$ Pu mixed oxide which had been $^{244}$ Cm oxide sample prepared 40 years ago. Plutonium ions were removed from the solution prepared by dissolution of $^{244}$ Cm- $^{240}$ Pu mixed oxide in nitric acid, by using an anion exchange resin column. Curium oxalate, a precursor compound of curium oxide, was prepared from the purified curium solution and supplied for the syntheses and measurements of the thermochemical properties of curium compounds.
