FIELD: precious metal recovery. SUBSTANCE: invention largely relates to recovering rhenium from solutions of molybdenum concentrate hydrometallurgical conversion including sorption of rhenium on low- basic anionite with secondary amino group as functional group, regeneration of anionite through desorption of rhenium by alkali reagent solution, and reutilization of anionite. According to invention, initial solution contains 30 to 200 g/l nitrate ion, and secondary amino group of anionite is formed in cyclohexylamine amination of styrene-divinylbenzene copolymer. EFFECT: optimized procedure. 1 tbl
