The effect of pyrite particle size on the

2018-1-1  In the presence of pyrite with fine particle sizes, gold extraction showed an increasing trend. This increase is attributed to the positive galvanic interaction between gold and pyrite (Habashi, 2013, Aghamirian and Yen, 2005). The highest gold extraction, i.e., 98%, was obtained in the presence of pyrite with a particle size of + 75–106 μm. It is obvious that the leach kinetics is also faster at this pyrite size
