Sulfide gold ores account for a large proportion of refractory gold ores, therefore, it is very meaningful to recover gold from sulfide gold ores (Ubaldini and Vegliò, 2000, Saba, 2011, Hammerschmidt, 2016). Moreover, the major gold leaching process for extracting gold from ores and concentrates is still cyanide leaching. Cyanide leaching process can effortlessly cause serious health and
