  • Gold cyanidation - Wikipedia

    OverviewHistoryChemical reactionsApplicationRecovery of gold from cyanide solutionsCyanide remediation processesEffects on the environmentAlternatives to cyanide

    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
