Trace element variations of pyrite in orogenic gold deposits

网页Pyrite (auriferous or gold barren), is the predominant metal sulfide in orogenic gold ores, and its trace element geochemistry has been widely used to reveal ore-forming processes (Cook et al., 2013, Gregory et al., 2016, Voute et al., 2019).

Recovery of gold from refractory gold ores: Effect of pyrite on

网页2021年4月5日The extraction of gold from refractory gold ores (RGOs) without side reactions is an extremely promising endeavor. However, most RGOs contain large amounts of sulfide, such as pyrite. Thus, investigation of the influence of sulfide on the gold leaching process is important to maximize the utilization of RGOs. In this work, the effects of
