Oxidation of GoldBearing Pyrite by Ammonium Persulfate

Aug 09, 2021 Abstract. Advanced oxidation processes (AOPs) are widely used in water treatment. Thus, we applied an FeSO 4 S 2 O 8 2 system to the oxidation pretreatment of Carlin-type primary gold ore. Based on this research, we have continued to explore the initiator (nZVI/FeO/FeSO 4) in the ammonium persulfate (APS) system.In this study, when the concentration of nano-zero-valent iron

Pyrite is the main inclusion in refractory gold ore, which complicated the gold extraction process significantly (Fraser et al., 1991).Several methods are proposed to open the inclusion (Boboev et al., 2016, Fomchenko, 2016, Li et al., 2009).Roasting and chemical oxidation is the most common method.

This process is convincingly shown on an SEM image, where particles of secondary gold are embedded in oxidized minerals (Fig. 8a,b,f), while tellurium is leached into solution and then deposited arbitrarily (Fig. 11a,b). This process is most probably responsible for the formation of the mustard gold that is widespread in the Gaching ores.
