FIELD: chemistry.
SUBSTANCE: method of extracting copper from an aqueous solution involves bringing an extractant in form of plant oil into contact with the solution. The mixture is stirred, settled and subjected to phase separation. Extraction is carried out from an aqueous solution with copper concentration ≤5 g/dm3 with ratio of the aqueous phase to the organic phase A:O≤8, pH 5.5-6.5 and 8.5-10.5, wherein pH is controlled for not more than 30 minutes.
EFFECT: high efficiency of extracting copper from aqueous solutions with simultaneous cost-effectiveness and safety of the process.
