FIELD: hydrometallurgy.
SUBSTANCE: hydrometallurgy used to extract rhenium from aqueous solutions. The method includes sorption of rhenium on activated carbon from aqueous solutions, its washing and desorption of rhenium with an ammonia solution. In this case, activated carbon is used, modified with single-walled or multi-walled carbon nanotubes with a content of 0.0001-0.1 g/g of coal.
EFFECT: increased degree of rhenium desorption at room temperature, increased concentration of commercial rhenium eluate, reduced sorbent consumption, improved sorption-desorption characteristics.
