Four types of fluid inclusions (FIs), including aqueous (type W), carbonic-aqueous (type C), pure carbonic (type PC) and solid-bearing (type S), are identified at the Tiemurt deposit. The early-stage minerals contain the C- and W-type primary FIs that are totally homogenized at temperatures of 330–390 °C with low salinities of 0.8–11.9 wt.% NaCl eqv.; whilst the late …
Free gold and gold wrapped in sulfides are considered as the object of gold floatation. However, floatation of free gold exhibits more variables in practice. In this study, improving gold recovery of a Pb–Zn sulfide ore from Yunnan Province, China, was investigated. The results show that free gold and auriferous sulfides account for 94.99 % of total gold. …

Historical and active mining has adversely affected the geochemistry of the Jiehe River in the Jiaodong Peninsula, which has the largest gold ore reserves in China. Water and sediment samples were collected along the 37.8 km long river during the critical low flow season. Samples were analyzed for their geochemical properties, total concentrations of As, Cr, Pb, …

The Yinshan Cu–Au–Pb–Zn–Ag deposit is located in the famous Dexing copper–gold polymetallic district in South China (Fig. 1).This polymetallic district consists of the Middle Jurassic (ca. 170 Ma) Yinshan Cu–Au–Pb–Zn–Ag deposit (950,000 tons of Cu and 107 tons of Au) (JGEB, 1996, Yinshan Lead-Zinc Mine, 1993, Wang et al., 2011b), the Middle …
From analysis of 52,760 assays from across the deposit it was found that there was a very poor correlation between gold and each of Fe, Zn, S, Pb, Cu, As and Ag, whereas Ag correlated reasonably well with both Pb and Zn. Results from EPMA shows that gold varies widely in composition from host-rock associated gold (96 wt.% Au) through more ...
The small-scale Balugou Cu-Pb-Zn skarn deposit (45 298 tonnages of ore at 0.1% to 3.99% Cu, 0.20% to 0.43% Pb and 0.76% to 10.92% Zn) is located in the Wulonggou area in the eastern Kunlun orogen, NW China. Ore deposition is spatially and temporally related with the pre-collisional Anisian Balugou granites (~244 Ma). The mineralization hosted by the contact …
