Elution behaviour of metals from carbon - SAIMM

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 carbon-in-pulp (CIP) process. In CIP processing, ore is mined, ground, and leached with alkaline cyanidic solution to solubilize the gold as a gold cyanide complex.

US3935006A - Process for eluting adsorbed gold and/or ...

A process is disclosed which is directed to recovering gold and/or silver values from activated carbon, wherein gold and/or silver has been adsorbed thereon. The process comprises eluting the activated carbon with water soluble alcohols or ketones either alone or with aqueous solutions thereof and a strong base may be added to further facilitate elution.

Activated Carbon forGold Recovery

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.

Durco Filters By Ascension Industries - Mining Filtration

Once stripped of gold by elution, the carbon solids are regenerated for reuse. As part of this regeneration process, Durco Filters presses are used to remove carbon fines generated during the many adsorption process steps, thus keeping all of the internal screens and filters free from premature plugging with carbon fines.
