  • The mechanism of elution of gold cyanide from activated

    When the concentration of cations in the eluant is high and no cyanide is present in the solution or on the carbon, very little desorption of gold is observed The quantitative effect of the concentration of spectator cations on the equilibrium for desorption of aurocyanide can be estimated from the elution profiles for gold and cations.

  • Elution

    Regeneration of the resin, , 610 Barren Carbon Return Following elution, barren carbon is either returned directly to the adsorption circuit or is regenerated The trend today is toward a horizontal regeneration-kiln For a smaller plant, this is located on top of the CIL tanks This allows the barren carbon to gravitate directly into the.

  • Elution behaviour of metals from carbon

    ELUTION BEHAVIOUR OF METALS FROM CARBON 475 Introduction Gold can be extracted industrially from ores by a variety of processes, and one of the most successful methods is the carbon-in-pulp (CIP) process In CIP processing, ore is mined, ground, and leached with alkaline cyanidic solution to solubilize the gold as a gold cyanide complex.

  • Inhibition of silicic acid elution during the regeneration

    To determine why silicic acid elution is often incomplete during regeneration of strong base anion exchange resin columns, an OH-type anion exchange resin (OH-type resin) adsorbing silicic acid was prepared and the desorption (elution) behavior of silicic acid adsorbed to the resin was examined by batch and column experiments It was first found that silicic acid adsorbed to an OH-type resin.
