    In 1783, Carl Wilhelm Scheele discovered that gold dissolved in aqueous solutions of cyanide. Through the work of Bagration 1844, Elsner 1846, and Faraday 1847, it was determined that each atom of gold required two cyanide ions, i.e. the stoichiometry of the soluble compound. The expansion of gold mining in the Rand of South Africa began to slow down in the 1880s, as the new deposits being found tended to pyritic ore. The gold could not be extracted from this compound with an…

     · How gold is extracted by Cyanidation Process Cyanidation is a method used in the extraction of gold from its ore. This extraction is done by converting the gold to a water-soluble form. The cyanidation process of gold extraction or the use of cyanide is the most common leaching process, used in the extraction of gold from its ores.
