Elution and Carbon Reactivation - Resource book

During the CIL process, gold is leached from the ore using an alkaline cyanide solution. The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed.

Processing, smelting and refining gold | World

More gold is recovered by cyanidation than by any other process. In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding

Gold Mining and Processing: Everything you

The Gold Mining Process. In addition to cyanide processing, gold ore is also processed with gravity separation. Advanced technology has enabled the amount of gold mined and processed to steadily increase over the years. For example, the worldwide production of gold in 2006 was 2360 metric tons. As of 2013, that number had climbed to 2770 metric tons. With continued advancements in mining
