Gold ores are commonly classified by the metallurgist into two major categories: free-milling and refractory ores. Typically, free-milling ores are defined as those where over 90% of gold can be recovered by conventional cyanide leaching. Refractory ores are defined as those that give low gold recoveries or give acceptable gold recoveries only
