Polymerization of uranyl ions and its role in ion-exchange extraction of uranium

Systematic investigations were performed of the intensification of ion-exch ange processes for extracting uranium from solutions and pulps during proce ssing of polymetallic mineral stock. The crux of the process developed cons isted in creating conditions under which polymer forms of uranyl are formed in solution and in the ionite phase. Several types of sorbents were studie d. It was shown that the sorption characteristics were improved, and the op timal conditions for the process were determined. The character of the poly merization. transformations of uranyl ions in the sorbent phase was determi ned. 5 figures, 11 references.
