Resolving the initial ore-fluid source and components is fundamental to understand the ore genesis. Although numerous stable isotope data from major Carlin-type gold deposits in the Youjiang basin have been published, the ore-fluid source remains disputed (Hu et al., 2017, Xie et al., 2018a, Jin et al., 2020).For example, Hu et al. (2002) proposed a meteoric water or …

The ore is sent into a single-cylinder hydraulic cone crusher for the secondary crushing. Thereafter, the gold ore is transferred to a multi-cylinder hydraulic cone crusher, where the ore is crushed further into finer material. From there, the crushed gold ore is sent to a ball mill, evenly as it passes through a vibrating screen for grinding.
