Abstract:

Scandium and thorium sorption from simulated uranium leach liquors by phosphorous containing ion exchange resins was studied. Increase of thorium concentration resulted in a decrease of scandium sorption by 26-65\%. Tulsion CH 93 resin was chosen for Sc separation from uranium leach liquors. It was shown that 180 g L-1 Na2CO3 allowed for elution 94.1\% of Sc and 98.9\% of Th in dynamic conditions. Using (NH4)(2)SO4 (50 g L-1) + ACBM (180 g L-1) mixture for primary Sc/Th separation at the resin/eluent ratio of 1:5 resulted in thorium desorption degree as high as 66-69\%, whereas scandium loss did not exceed 10\%.
