FIELD: extraction of matters with use of organic agents out of aqueous solutions, possibly in ferrous and non-ferrous metallurgy. SUBSTANCE: method comprises use of mixture of oleic acid and triethanoamine as extraction agent for extracting tin out of aqueous solution at pH no more than 3 or equal to 3 at continuously controlling optimal pH value for time period no more than 1-3 hours. It is possible to use for extraction technological lubricant containing inert diluent at next relation of ingredients (mass %): oleic acid - (10-12); triethanolamine - (4.5-6); machine oil (inert diluent) - the balance. EFFECT: effective small cost process for extracting tin with use of less volatile readily available extracting agent. 2 cl, 1 tbl, 1 ex
