ELUTION BEHAVIOUR OF METALS FROM CARBON 475 Introduction Gold can be extracted industrially from ores by a variety of processes, and one of the most successful methods is the carboninpulp (CIP) process. In CIP processing, ore is mined, ground, and leached with alkaline cyanidic solution to solubilize the gold as a gold cyanide complex.
Oct 11, 2006· 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.
spent activated carbon containing onlysingle ordefined adsorbates, thermal methods havetobeusedwhenthe spent carbon isloaded withaheterogeneous mixture ofadsorbates suchasthose normally present inindustrial process streams oreffluents. Thestepsinvolved inthermal regeneration aredescribed, together withtheoperating
From the contact tanks the loaded activated carbon is transferred to the elution and regeneration phase. The now barren carbon is returned to the contacting phase where any losses are made up with activated carbon. The gold is then recovered by a process known as electrowinning.

This is essential in order to retain adsorptive properties of the carbon to be close as possible to that of new/ fresh carbon. The Carbon Regeneration System sufficiently processes the carbon and reactivates the carbon to be used back in the original intended process.

carbon is most often used to adsorb gold from dilute alkaline cyanide solutions. The gold is dissolved as the Au(CN) 2complex and is recovered from the solution by CarboninPulp (CIP) or CarboninLeach (CIL) processes. Activated carbon loaded with gold must be treated by an elution step to desorb the gold for subsequent recovery.

to the top of the carbon bed and is sprayed on the carbon. The downflowingcondensate washes the gold values from the carbon particles into the boiler section below. (3) Alcohol Recovery. When desorption is completed, as indicated by gold solution concentration reaching a constant level in the column boiler, alcohol recovery commences.
adsorption experiment, the slower Cd elution is. The elution of Cd ions is slow and requires a large number of bed volumes when the metal concentration is high; however given that the lean feed is found to be better for metal recovery, as illustrated by the breakthrough curve, the elution process will be also better, for the lean metal
