    Gold Recovery Process For gold recovery, water and a cyanide such as calcium cyanide, sodium cyanide, or potassium cyanide, are added to ore or scraps to form a slurry. The gold will leach out and mix with the cyanide into a solution. Activated carbon is then used to separate and store the gold, which is removed as the final step of the process

    Here, the gold is adsorbed onto the surface of the activated carbon, now considered loaded. The gold can then be desorbed from the loaded carbon in a process known as elution (this step is often referred to as stripping), which produces a high gold concentrate solution from which gold can be electrowon

    The gold adsorbs onto the surface of the carbon. The loaded carbon is periodically removed from the columns, and sent to the stripping circuit. The carbon is then generally subjected to a heated solution (200 deg to 250 deg F) of (1%) sodium hydroxide and (0.1%) cyanide and the gold is re-dissolved and removed from the carbon surface

    how is the gold removed from activated carbon

    After the gold is removed from the activated carbon the gold is placed in vessel where it is attached to steel cathodes where it is usually removed with a pressure water spray and placed in Dore bars. Activated carbon can help to purify gold over 99 making its role in modern gold extraction very important. Sources. Contact Supplier
