Leaching of gold and copper minerals in cyanide deficient

Aug 01, 2005 The concept of leaching copper–gold ores using leach solutions which contain Cu(CN) 3 2− was investigated. Gold leaching occurs in air saturated Cu(CN) 3 2− solutions at a much slower rate than in free cyanide solutions. A similar gold leach rate is observed when copper is alloyed with the gold.
