    The principal method used in the extraction of gold is cyanidation. The basic principle of the cyanidation process is that cyanide solutions have a preferential dissolving action for the precious metals contained in an ore (Marsden J., House I., The Chemistry of Gold Extraction, Chapter 6, published by Ellis Horwood Limited, 1992, page 259 308).
