The final step is to cast the gold into electrodes orThe most important purification process in gold mining is cyanidation. Sodium cyanide solution in the presence of air causes gold to enter into solution. Good quality ores give up their gold under cyanidation in what is called vat leaching. Lesser quality ores require heap leaching, which involves huge piles of ore being repeatedly re-sprayed ...
