Gold Refining | OceanaGold
The gold content is captured in a 'mud bag' around the anode. It is washed and dried, then melted and refined in a chlorination process where chlorine gas is introduced into the melting crucible. Gold is separated from the remaining base metals and is poured into granules or bars for commercial sale. References and Acknowledgements
How is gold refined into high-purity bullion? | Provident
Gold panning is a simple and rudimentary form of this process. Physical sifting and separation, at best, are just initial steps.
