Recovery of Silver, Gold, and Lead From a Complex

Recovery of gold and silver has been based on caustic cyanidation ~ince the 1890's. However, not all ores are amena­ ble to cyanidation, particularly those containing sulfides (chalcopyrite, sphal­ erite, galena, etc.). Gold and silver extraction is usually low and cyanide consumption is high because of base metal
