Here we report a rare example of the association of Cu and Pb-Zn in the Tianbaoshan deposit of the upper Yangtze province, South China. In this deposit, co-existence of Cu and Pb-Zn ores (Fig. 2 b) with enrichment of Cd, Ga and Ge has been previously noticed (Zhou et al., 2013c, Sun et al., 2016, Zhu et al., 2016). However, the significance of ...

The results of isothermal adsorption of different heavy metals by sediments are shown in Fig. 2.In general, the isothermal adsorption curves of Cu 2+, Zn 2+, Pb 2+ and Cd 2+ by sediments showed a similar changing trend. At the lower concentration range (< 100 mg/L) of adsorption equilibrium solution, the adsorption amount of heavy metals on sediments …

Table 3 shows that Cu, Zn, Pb, Cd, and Cr contents are equal to 425–526, 574–1134, 321–356, 0.72–4, and 99.69–576 ppm, respectively. These levels are far above the average concentrations in the limit values (150 ppm for the Cu, 150–300 ppm for Zn, 50–300 ppm for Pb, 1–3 ppm for Cd, and 2.677 ppm for Cr) (Kouame et al. 2006). The ...

It contains ∼26 Mt Zn–Pb ore (7.76–10.09 % Zn, 1.28–1.50 % Pb and 93.6 g t −1 Ag) and >0.1 Mt Cu ore (2.55 % Cu). In this study, the detailed mineral textures, mineral chemical and sulphur isotopic compositions of the various sulphides have been analysed to constrain the abnormal enrichment mechanism and mineralization relationship.

Cu, Mn, Zn, Pb, and Ni was determined. In order to determine the controlling factors for the flocculation of Cu, Mn, Zn, Pb, and Ni during estuarine mixing, physico-chemical parameters were measured. EC, DO, pH, T, and salinity of samples were measured by using WTW multichannel portable apparatus (model 340i). Eh was measured by ORP meter ...

The concentrations of Pb, Cd, Cu, Zn and Ni in the solutions were analysed by ICP-MS with three replicates for each analysis (ICAP 6200, USA Thermo Fisher). 2.6 Statistical analysis. All results were expressed as the mean values ± SD. Statistical analyses were performed using SPSS version 19.0 for Windows (SPSS, Germany).

The Mount Isa Zn-Pb-Cu-Ag deposit contained almost 30 million tons (Mt) of base metals, prior to mining, in spatially separate Cu and Zn-Pb-Ag orebodies. The origin of the Zn-Pb-Ag ores is debated due to apparently conflicting features at intermediate to microscales. Ambiguity is associated with small-scale features, which can be interpreted ...

The variation in δ 65 Cu AE647 (δ 65 Cu max-min) was larger than that of δ 66 Zn IRMM3702 (i.e., δ 66 Zn max-min), and the isotope values of Zn and Pb (206 Pb/ 207 Pb) tended to increase with the concentrations of these elements. Meanwhile, the fine RDS particles (< 63 µm) had similar Cu, Zn, and Pb isotopic compositions to those of TSS.
