Charcoal has been known for a considerable length of time to have the property of recovering gold, silver, and copper from cyanide solutions of these metals. Quantitative data that may shed light on the mechanism of the removal of these metals is very limited except that charcoal in a form known as activated has the power to abstract gold and silver in considerable quantities from the above solutions.
