Investigation of the sorption method of processing molybdenum-containing raw materials to extract rare metals

The article investigates the sorption method of concentrating rare metals on various sorbents (brands “Purolight”: A-100, A-170, A-172 and BO-020) determines optimal conditions for their extraction. It is shown that extraction molybdenum sorbent “Purolight A-100” was 98%. proposed mechanism consists in formation complexes with functional phosphor basics sulfate groups sorbents. Sorption rhenium Purolite A-170 93%. BO-020 described by Langmuir equation a maximum static exchange capacity 94%. Based desorption kinetics ion-exchange sorbents, it proceeds most efficiently low-basic anion exchangers A-100 Mo respectively, after double recleaning “rough” concentrate, ammonium qualification obtained AR-0.
