The chemicals used in processing are in a much lower volume than the other types of wastes, but can be of a high risk due to high toxicity, even in small concentrations. A common chemical used in gold extraction is cyanide. The cyanide dissolves the gold to an aqueous solution, making it a simple and cost-effective technique.
