A Thermodynamic Analysis on the Roasting of Pyrite

In terms of the auriferous pyrite (i.e., sulfidic gold ore), gold often occurs as submicroscopic particles that are easily enclosed in crystal lattices of pyrite [ 3 ]. Consequently, gold is difficult to be exposed unless undergoing ultrafine grinding, resulting in high energy consumption [ 4 ].get price
