Abstract: The leaching efficiency of gold from some Saudi ores by the toxic cyanidation process is as low as 6080%. Mining tailings of these ores contain considerable amounts of residual gold and toxic cyanide ion. These tailings are stored in massive ponds (tailing dam) containing considerable amounts of gold and pose environmental hazards.
