Establishing thE ProcEss MinEralogy of gold orEs

Process mineralogy can play an important role in optimizing the metallurgical processing of gold ores. It is widely used to characterize gold in gold ores and mill products, and to determine the mineralogical problem(s) causing gold losses. The information acquired from a process mineralogical study can be used as a basis for a metallurgical testwork program for process design or optimization. Ideally, a
