METHOD FOR INTENSIFICATION OF SORPTION OF NOBLE METALS WITH HELP OF NANODISPERSED SORBENT Russian patent published in 2016 - IPC C22B3/24 C22B11/00

Abstract RU 2582838 C1

FIELD: metallurgy.

SUBSTANCE: invention relates to production of nano-disperse sorbent of metals and to use of obtained sorbent for sorption process intensification and can be used in hydrometallurgy of noble metals. Method of extracting noble metals from solutions involves sorption on organic sorbent [perhydro(1,3,5-ditiazine)-5-yl]-hexane of general formula C₉H₁₉S₂N. At that, sorption is carried out using sorbent in form of emulsion particle size produced by radiation of sorbent with ultrasound in aqueous medium.

EFFECT: use of sorbent in maximum milled state (colloid) that allows achieving uniform and stable distribution of sorbent in aqueous solution.
