  • Ion exchange resins for gold cyanide extraction containing

    The piperazine resins extract gold via two mechanisms: (a) ligand substitution reactions at pH > 7.05 (p KH (a)) or (b) anion exchange reactions via the quaternary ammonium groups at high pH values. Extraction profiles were S‐shaped (cf. Fig. 10) with 50% extraction ability at pH 8.0.

  • Extraction of gold, palladium and platinum from chloride

    The method of extraction of gold, platinum and palladium from hydrochloric acid solutions, including their adsorption on the anion exchange resin and desorption, characterized in that the sorption was carried out at slightly basic anion exchangers and desorption is conducted with a solution of a mixture of salts of sodium sulfite Na 2 SO 3 and

  • Carbon and Resin Technologies for Gold Recovery SGS

    In recent years, resin is replacing carbon as the gold recovery substrate of choice. SGS is the world leader in the development of this technology. The process used in resin recovery is similar to carbon, but the gold is adsorbed onto solid spherical polystyrene resin beads rather than activated carbon grains.

  • Mining & Smelter - Products - PT Lautan Luas Tbk.

    In recent years, resin has begun to replace carbon as the gold recovery substrate of choice, for both resin-in-leach and resin-in-Pulp. The process used in resin recovery is similar to that of carbon, but the gold is adsorbed onto solid spherical polystyrene resin beads rather than activated carbon grains.

  • Purolite Ion Exchange Resins for Metals Recovery Applications

    Gold Gold mines in the Former Soviet Union countries mainly use IX resin for the recovery of gold, employing resin-in-pulp (RIP) technology, whereas the Western world tends to use activated carbon in carbon-in-pulp (CIP) or carbon-in-leach (CIL) processes. In recent years, however, there has been a move towards the use of IX resins.
