The mineralogy of gold ore deposits ranges from freemilling, metal oxide ores, to sulphides. The sulphide ores tend to be refractory to leaching when employing a normal cyanidation process. Recoveries of gold, when employing a normal cyanidation process in the treatment of sulphide ores, tend to be less than 80%.

Abstract. The objective of milling gold ores is to extract the gold for the highest financial return. To recover the maximum amount of gold, the ore must be finely ground in order to liberate the gold particles for gravity separation and/or chemical extraction.
