  • AARL Carbon Stripping System Operation Elution

    During this stage a 2 caustic 3 cyanide solution mixture is re circulated through the loaded carbon in the elution column until such time as a predetermined top of column temperature is reached By this time most of the gold and silver on the carbon will have been desorbed into solution and both the carbon and the solution will have reached an optimum temperature for the subsequent

  • OPTIMIZING THE OPERATING CONDITIONS OF GOLD

    Base metals that have not been stripped during the elution will build up in the carbon and will affect the gold loading in the CIP process The continuous decrease of gold content in the stream and the variability of flow rate and temperature affect the elution and electrowinning processes Low grade eluate tends to be

  • Effect of Calcium on Gold Stripping Efficiency

    The elution efficiency achieved from non acid washed carbon is very sensitive to water quality The elution efficiency will decrease with increasing ionic strength of the water used for elution Work carried by Mintek at Grootvlei in 1981 showed a barren carbon grade of 60g t Au from the elution of a loaded carbon containing 1 9 Ca
