Gold extraction - QueensMineDesignWiki

The first step in gold extraction is leaching the gold which turns gold in solid form to liquid with cyanide in the presence of oxygen. Next, the gold adsorbs to the activated carbon. Finally, the carbon and gold complex is sent to elution where it is washed, and transferred to electrolysis where the gold is fully recovered.
