Refractory gold ores are those that do not yield high gold recoveries in conventional cyanide-leaching circuits, even when the ore is finely ground. The cause of low gold recoveries can be either through the presence of naturally occurring ‘preg robbing’ carbonaceous materials or gold physically ‘locked’ in sulphide minerals.
