Gold Precious Metals Extraction Recovery CPL

Mining. The best known application for activated carbons in the mining sector is for the extraction and recovery of gold (Au), although it is also used for some other precious metals. In the gold recovery industry, there are three main methods for extraction of the metal, all of which use granular activated carbon in the recovery of gold from

Reactivation Process of Activated Carbons: Effect on

If the activated carbon is subjected to a thermal reactivation, the iodine number increased with the rise in temperature [ 15, 25, 30 ]. Another important property of an activated carbon is the gold adsorption value (k), which should be between 15 and 25 mg Au/g AC in order to use the carbon satisfactorily in the CIP process [ 15, 26, 30 ].

Ultrasonic elution of gold from activated carbon

2003-3-1  Activated carbon is the most widely used sorbent for gold recovery from cyanide solutions. One of the slowest steps in the extraction of gold by CIP/CIL techniques is the desorption of gold from the loaded activated carbon.
