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

elution column manufacturer steel fabrication elution

elution columns. among the major stainless steel products that stegel is provisioned to manufacture are elution columns which are used for gold recovery. the use of elution columns in gold recovery is a cost-effective method of recovering gold from the sediment in mine dumps and other areas in which gold particles reside.

modelling of the aarl elution process - sciencedirect

because of the interest in cyanide-free modelling of the aarl elution process 601 elution each set of the presoaked carbon was washed to neutrality before being subjected to elution at 125 for 6 hours. washing of the carbon was done to remove degradation products and adsorbed cyanide ion caused by presoaking in caustic cyanide solution.

especially the bottom strainers of the zadra . elution this model was incorporated in a material balance for a series of well-mixed reactors simulating the effects of an elution column and

elution and carbon reactivation - resource book

the column has a volume of 11.3m 3 (1 ‘bed’ volume) which can hold approximately 6 tonnes of carbon. external lagging (insulation) lines the exterior of the column to prevent heat loss during elution.various valves are installed at the top and bottom of the column for; filling/eduction liquid circulation and pressure relief.

elution acid wash & carbon transfer vessels

our elution and acid wash columns are optimally designed for plug flow of eluate or fresh water for eluting gold cyanide complexes from activated carbon recovered from cip/cil gold adsorption circuits. designed and constructed to a range of available pressure vessel codes including asme viii en13445 b51-14 or as1210 the vessels can be manufactured from carbon steel boiler plate for
