Establishing thE ProcEss MinEralogy of gold orEs

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 with the use of significantly more reagents or more complex pre-treatment processes. Based on the mineralogical characteristics and mineral processing techniques required, gold ores
