In order to characterize antimony (Sb) isotope fractionation in hydrothermal systems, we present Sb isotope compositions of primary stibnite ores from a large Sb deposit in south China. A total number of 39 analyses reveals a large δ123 Sb range of −0.27 to +0.86‰, representing an up to 1.13‰ variation in this hydrothermal …

Phase Composition The XRD patterns of the tailings were shown in Fig. 2. The results show that the antimony ore tailings mainly include stibnite, antimony sulfide, and quartz. Other minerals may not be detected because of the low content. Heavy Metals in Tailings The situation of heavy metal in tailings samples are given in Table 1.
