Model studies on precipitation of ammonium uranyl tricarbonate from kerosene solutions of di-(2-ethylhexyl) phosphoric acid and trioctylphosphine oxide

Creators

Description

The results of the model studies on precipitation of uranium (6) from kerosene solutions of D2EHPA and TOPO, using ammonium carbonate are presented. The process product is uranium concentrate in the form of ammonium uranyl tricarbonate (NH4)4[UO2(CO3)3]. The carried out investigations upon the effect of the process parameters concerning the precipitation of uranium can be used for the determination of data needed for scaling up the process to the pilot plant scale. 12 refs., 4 figs., 3 tabs.
