Trivalent actinide separation from PUREX raffinates

After five years of cooling, one ton of a PWR uranium oxide spent fuel (burn-up of 60 GWd/t) contains 785 g of americium (62.4% of Am-241, 37.4% of Am-243, and 0.2% of Am-242m, all three LLRN), 135 g of curium (8% of Cm-245, 1% of Cm-243, 1% of Cm-246, all three LLRN, and 90% of Cm-244, a short-lived radionuclide), but around 60 kg of fission products, one third of which are the lanthanides.
