Recovery of Gold from Solutions

  • J. C. Yannopoulos


Cyanidation has been used to extract gold (and silver) from ores, concentrates, and calcines since the 1890s. The precipitation of gold from cyanide solutions by zinc cementation was patented in 1884 and was applied industrially as early as the cyanidation process.
