Atmospheric Elution Process

The most operable elution plant design incorporates a single batch column which allows the acid wash and elution processes to be carried out in the same column This system is ideal for the small elution plants treating up to 2 tons of dry carbon per batch The combined process is easily automated and a full cycle takes less than six hours in ....

Elution Process Stages Column Loading Carbon is removed from the circuit from tanks 2 and 102 The slurry is pumped to the loaded carbon screen where the carbon is screened from the slurry, which is returned to the tanks Spray bars fitted to the screen wash residual slurry from the carbon The carbon discharges off the end...

This is due to its significant cost advantage over atmospheric pressure Zadra systems This stage continues until five bed volumes of water have passed through the column 2 Potable water then continues to flow through the system as per the elution stage for another twenty minutes, this taking some of the heat out of the carbon and the thermocal...

The elution step may be further divided into two major stages; carbon preheat and elution proper Here a separate column is provided for acid washing The advantages of this are dubious in that there would be more than enough time in a twenty four hour period for both steps to be completed in one column...

Elution of AM-2B resin is similar to that of Minix; but a longer elution time seems to be required (Bolinsky and Shirley, 1996)The process includes a series of elutions, contacting the loaded resin with different solutions The elution flowsheet differs from plant to plant, and some of the steps described below are optional...

some of the advantage of the water elution used in AARL stripping (4) In situations where large amounts of copper load onto carbon with the gold and silver, a two stage strip may be beneficial Copper may often be selectively eluted with a cold caustic/cyanide solution This is then followed by one of the standard stripping methods...

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...
