    What is Gold Cyanidation? with picture - wiseGEEK

     · Gold cyanidation, also called cyanide leaching, is It uses cyanide to dissolve the gold within the rock, which, itself, is not soluble in cyanide. The gold is then drawn out in a liquid form that can be treated to remove the cyanide. Almost 90% of all gold extracted commercially is done so by cyanidation.
