The prepared desorption solution containing 4% NaCN and 2% NaOH goes through heat exchangers to raise the temperature of the solution before entering the elution (desorption) column from the bottom. The pregnant solution is sent to the electrolyte tank for electrowinning. Barren carbon after desorption is
the process of gold elution. Carbon in pulp is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process Introduced in the early 1980s Carbon in Pulp is regarded as a simple and cheap process As such it is used in most industrial appliions where the presence of ...

Desorption is accomplished by contacting char containg metal values in a closed chamber under pressure with the saturated water ammoniaThe foregoing procedure was repeated for 6 cycles with no change in the adsorption, elution, or regeneration characteristics of the activated coconut carbon.
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.

25/06/2021 · Carbonbased adsorbents, such as activated carbon, carbon nanotubes, carbon black, or carbon fiber are usually considered as the best adsorbents, and have been used for more than 2000 years in the adsorption process (Tagliavini et al. 2017).Activated carbon is one of the most widely used materials due to its novel microporous structure and specific surface area.
The protonated alga Sargassum muticum was employed in batch desorption studies to find the most appropriate eluting agent for Cd(II)laden biomass regeneration. Eleven types of eluting solutions at different concentrations were tested, finding elution efficiencies higher than 90% for most of the desorbents studied. Total organic carbon
