Accumulation of Cr, Cd, Pb, Cu, and Zn by plants in tanning

Unlike Cr, Cu, Cd, and Pb, the maximum Zn concentration was not found in plants at site HN-4 or HN-5, but in A. philoxeroides (365 mg kg −1) at site HN-3. Furthermore, Z. candida and C. dactylon at site HN-2 and even C. rotundus at Site HN-6 contained Zn concentrations greater than 200 mg kg −1, exceeding the highest Zn …

Contrasting regimes of Cu, Zn and Pb transport in ore-forming

Sulfur and chlorine are the two most important ligands accounting for metal transport in the upper crust. In this study, four metal- and sulfur-saturated model fluids with varying salinities and redox states were simulated in the Fe-Cu-Pb-Zn-Au-S-C-H-O system, over a wide pressure-temperature (P-T) range (50–650 °C, 0.8–5.0 kbar), in order to …

Precipitation of Heavy Metal Ions (Cu, Fe, Zn, and Pb) from …

Metal mining extraction and concentration need water. The recycling of liquid effluents reduces its consumption. This recycled water must contain low concentrations of metals. This project's first objective was to start up a laboratory-scale upflow anaerobic sludge blanket (UASB) reactor for biotransforming metal sulfates into metal sulfides of …

Assessment of heavy metal availability (Pb, Cu, Cr, Cd, Zn) and

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).

Evaluating Sn mineralization potential at the Haobugao skarn Zn–Pb

1. Introduction. Skarns represent one of the most common genetic types of ore deposits. There are more than 1600 skarn deposits in the world (Meinert et al., 2005), although the number could be much larger due to the new discoveries after 2005 (e.g., Chang et al., 2019).In China, the 386 skarn deposits (as of 2019) account for 87% of the …

Regional background concentrations of heavy metals (Cr, Co, Ni, Cu, Zn

The coefficients of variation (CVs) for mean metal concentrations of Cu, Zn, and Pb were 0.62, 0.37, and 0.29, respectively, while those for other metals except Li showed values in the region of 0.19–0.23. Although the spatial distribution of Pb was similar to those of Cu and Zn, the CV of Pb was in between that of Ni or Cr and Zn.
