Sorption processes in the hydrometallurgy of refractory metals

The results obtained at the All-Russia Scientific-Research Institute of Che mical Technology on the use of sorption processes in the hydrometallurgy of refractory metals and purposeful synthesis of the required ion-exchange ma terials are presented. It is shown on the basis of synthesized ionites that the ion-exchange technology is efficient for processing complex technologi cal solutions for different types of polymetallic raw materials, including uranium. ores, concentrates from enrichment of ores of refractory metals, c ommercial products, and waste solutions. The technological schemes developed have been successfully adopted on ail i ndustrial scale. 3 figures, 1 table, 12 references.
