FIELD: hydrometallurgy; chemical, microbiological and other industries. SUBSTANCE: extractor includes extraction and re-extraction chambers which are connected in their upper and lower parts by means of connecting passages and are provided with distributing devices, as well as with pipe unions for delivery and discharge of extracting and adsorbing phases. Extraction and re-extraction chamber are interconnected through washing chamber located between them. All chambers are provided with separator zones which are located near inlet holes of connecting passages. Such construction makes it possible to combine extraction, re-extraction and washing processes in one apparatus. EFFECT: enhanced efficiency. 5 cl, 7 dwg
