Feasibility Study of Differential Flotation of Cu–Pb–Zn …

Aug 28, 2020 · This study aims to investigate the effects of pH and chemical reagents to model and optimize the flotation process of a complex lead ore containing 2.44 wt% Pb.

Super-stable mineralization of Cu, Cd, Zn and Pb by CaAl …

Apr 5, 2023 · Soil pollution caused by potentially toxic metals (PTMs) is a world-recognized environmental problem. The excessive accumulation of PTMs (e.g., Cr, Cu, Zn, As, Cd, Hg and Pb) in soil has seriously affected the grows of crops and the quality and safety of food, and further affected human health through the food chain [19], [21], [30].Various physical remediation …

Pb-Zn-Cu accumulation from seafloor sedimentation to …

Aug 1, 2019 · The Tiemurt Pb-Zn-Cu deposit is situated in the southern margin of the Chinese Altay Orogen (Fig. 2).It was first discovered in 1987 with contained metals of 0.29 Mt Pb + Zn and 0.14 Mt Cu (Wan et al., 2010a).Some geological and geochemical characteristics of primary VMS mineralization are preserved at Tiemurt, but the major Pb-Zn-Cu mineralization is adjacent to …

Differential Metal Tolerance and Accumulation Patterns of Cd, Cu, Pb ...

Dec 14, 2017 · In this study, we investigated the bioaccumulation, tissue distribution and physiological responses to different metal concentration (0.2 and 2 mM) and time of exposure of 1, 2 and 3 weeks with cadmium (Cd), copper (Cu), lead (Pb) and zinc (Zn) using the model liverwort Marchantia polymorpha. Our data showed, on one hand, a significant enrichment and …

Ecological Risk Assessment of Cu, Ni, Cd, Hg, Zn, Pb and As …

Jul 30, 2024 · The mean values of RAC were in the sequence of Cu > Zn > Cd > Pb > Ni > Hg > As. The results of RSP indicated that the ecological risk levels of Cd, Ni, Cu, Zn, As, and Hg in the soils were low, and Pb was the most significant potential risk factor among all elements. The findings can be used to practice sustainable soil management in the area.

Distribution of Fe, Zn, Pb, Cu, Cd and As from mining wastes …

Aug 1, 2012 · Consecuente con la mineralogía de los yacimientos explotados, los jales de Nacozari contienen concentraciones totales bajas de As (8.9 mg kg-1), Pb (< 20 mg kg-1) y Zn (91 mg kg-1) y ...

The Phytoremediation Potential of 14 Salix Clones Grown in Pb/Zn and Cu ...

Jan 29, 2024 · Willows are suitable candidates for phytoremediation projects. A pot experiment was conducted to evaluate the potential of using Salix unrooted cuttings for the phytoremediation of lead/zinc (Pb/Zn) and copper (Cu) mine tailings. Cuttings of 14 Salix clones were directly rooted into pots containing mine tailings. The 14 clones showed different levels of tolerance to tailing …

Decoupling of Cu and Zn in sediment-hosted base metal …

Aug 1, 2024 · The giant Cu-Pb-Zn polymetallic Baiyangping deposit in the northern Lanping Basin shows pronounced zoning of Cu-rich orebodies related to deeper reverse faults and Zn-Pb orebodies related to shallower strike-slip faults. The fluid inclusions in the Cu-rich stage show temperatures of 210–300 °C, salinities as low as 4 wt% NaCl equiv., and Na ...

Transfer Mechanism, Uptake Kinetic Process, and …

Dec 1, 2023 · Within the RMC, Rogozna mining projects are composed of the Gradina (reduced Au + Zn ± Cu), Medenovac (oxidized Zn + Cu + Au), Copper Canyon (reduced Au + Cu) and Šanac (Au + Cu ± Zn ± Bi) deposits, mainly hosted in skarn bodies and to a lesser extent the overlying volcanic rocks, as well as vein hosted epithermal Pb + Ag ± Zn ...

Contribution à l’étude des minéralisations à …

Feb 24, 2015 · 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 compare the …
