    Of the gold minerals, calaverite [AuTe 2] Arsenopyrite was observed to be more reactive than pyrite, chalcopyrite, galena, and sphalerite. Oxidation of arsenopyrite led to the formation of scorodite on the surface. The activation energies for arsenopyrite oxidation varied from 18 kJ mol –1 at 0–25 °C, to a slightly negative E a of−6 kJ mol −1 at 25–60 °C. Rimstidt et al. (1994

    At first glance, pyrite and chalcopyrite are similar in their color and shiny metallic luster. However, the two can be distinguished by their hardness. Chalcopyrite is a soft mineral that can be scratched by a nail, while pyrite is hard enough that a nail cannot dig into its surface. Unlike pyrite, chalcopyrite also weathers to display an

    Chalcopyrite, a major mineral for copper production, is not exceptional. It is often in association with iron sulphide minerals, particularly pyrite and minor amounts of sphalerite and molybdenite (Habashi, 1987; Wang, 2005). Recent studies indicate that the selective separation of chalcopyrite from pyrite is very
