Fouling of carbon, regeneration and Elution – Gold

02/04/2016  Fouling of carbon, regeneration and Elution In all plant circuits, the carbon activity quickly deteriorates from stage to stage but the reasons why it should do so are complex. It is known that the carbon activity is enhanced by lower pH, higher temperature; the presence of Ca2*, Mg2*, Na*; and by small particle size.

Elution and Carbon Reactivation - Resource book

ELUTION CARBON REACTIVATION 8888 Elution Elution is the actual gold removal stage. Potable water (low ionic strength) is pumped through the column at high temperature (115°C) and pressure (230 kPa). High temperatures are used as the gold loading capacity of carbon is reduced

Elution and Carbon Reactivation - Resource book

Thermal reactivation (regeneration) simply involves heating the carbon in the presence of steam to 750°C in a gas fired reactivation kiln. The combination of high temperatures and the steam environment vaporises the organic foulants, returning activity to the carbon. The reactivated carbon is returned to the circuit and the adsorption, elution (desorption) and reactivation cycle starts anew ...

31/03/2016  Elution and Carbon Cool. During the elution cycle, water is drawn from the potable water tank and pumped through the heat exchanger via valve AV 409 into the column. The water then flows up through the column, taking with it gold that has been freed into solution during the preheat stage. This pregnant solution then flows out of the column through the inline filter and the heat exchanger, then ...

Thermal desorption of mercury from gold-loaded

01/04/2012  This may be because the elution time is not long enough to give higher elution since desorption of gold from the loaded activated carbon is one of the slowest steps (Pyke et al., 1997). The elution time used in industry is generally more than 8 h, such as 8–12 h in the pressurized Zadra process, while it is only 3 h in total in our case.

Improvement in the process for the regeneration of spent activated carbon combining an aqueous alkaline solution and an organic solvent, such as a lower alcohol. The spent carbon is first contacted in a column under practically static conditions, and at between 25* and 90*C for 30 minutes to 2 hours with an aqueous alkaline solution, preferably 0.5 to 25 percent by weight sodium hydroxide.

Carbon Stripping – Denver Mineral Engineers

After the desorption vessel has been filled with loaded carbon and solution flow is started, the only operator attention required is periodic system checks typical of any process plant operation. The main disadvantage of the original Zadra process is its low rate of desorption. It is much slower than the alternatives. This necessitates larger carbon inventories and larger equipment than other ...

Ion exchange regeneration methods - Dardel

Ion exchange operation is basically discontinuous: a loading phase, called service run, is followed by regeneration of the exhausted resins. There are two main methods for the regeneration process: Co-flow regeneration, where the fluids are flowing from the top to the bottom of the column both during the service run as well as during regeneration.
