concentrate; calcine; dust; cyanidation; carbonaceous matter 1 Introduction With rapid depletion of free-milling gold ores, the proportion of gold extracted from refractory gold ore is increasing [1-3]. Refractory gold ores are defined as ores for which the leaching efficiency of gold by cyanidation is less than 80%, even after fine grinding [4,5]. Gold in refractory gold ores can be effectively......
