  • Electrowinning an overview ScienceDirect Topics

    Operation of the electrowinning process differs depending on the elution procedure that is used. In the case of Zadra elution, where the electrowinning cell is in series with the elution column, the column and cell must be designed to elute and recover the gold by recirculation of the eluant until the gold content of the eluted carbon is low

  • AARL Carbon Stripping System Operation: Elution

    AARL Carbon Stripping System Operation: Elution Electrowinning Elution stage. During this stage the gold and silver desorbed off the carbon during the preheat .* is washed out of the column into the eluate tank. This stage takes 2 1/2 hours and involves the use of 5 bed volumes of potable water (21.6 cubic metres). The critical factor during this stage is temperature. It has been

    conditions, elution (desorption) of gold from the carbon occurs. The main factor that makes desorption or stripping a simple process is the fact that gold will only adsorb onto carbon at low temperatures.

  • Elution of Mercury Silver Gold from Anion Exchange Resin

    Elution procedures for mercury, silver, and gold discussed in previous sections suggest a possible flowsheet (fig. 2). To evaluate the elution scheme, loaded strongbase resins were contacted with 2N H2SO4 to elute mercury, with 200 g/L NaCl in 1N HCl to elute silver, and with 0.75pct NaOCl In 150 g/L NaCl plus 5 g/L NaOH or 2M NaClO4 to elute gold. Two series of tests were conducted.
