How is gold mined? GoldTraders (UK) Ltd
The final category of gold mining is the processing of Gold ore. This method is largely becoming deprecated as the yield of Gold is often very low and the environmental impact and costs of the operation are substantial. The Gold ore is finely crushed rock or earth containing trace amounts of Gold which are extracted using a chemical process.

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.
