The Oligocene to Miocene Baiyangping Cu–Co and Pb–Zn mineralization was deposited during the collision of the India and Asia continents. The mineralization is hosted in veins in faulted carbonate and clastic rocks, which act as fluid pathways. A detailed fluid-inclusion analysis and C–O–S isotopic study are reported, focusing on the …

The Cu–Pb–As–Zn mineralization of Cap Garonne (Le Pradet, Provence, France; Fig. 1) is located in Triassic siliciclastic rocks, a few meters above the contact between Paleozoic and Mesozoic rocks (Fig. 2). It is the only known Cu–Pb–As–Zn association of Provence and surrounding areas, covering only a few hectares.

As a result of little attention to the Pb-Zn mineralization in the Cu-Co-Pb-Zn system, it is unclear about the discrepancy among these deposits. The Jingchong Cu-Co-Pb-Zn deposit with reserves of 0.24 Mt Cu, 3718 t Co, 12250 t Pb and 72831 t Zn, is characterized by lower Cu-Co and upper Pb-Zn orebodies (Wang et al., 2017, Wang et …

Recoveries of Cd, Pb, Fe, Zn and Mn showed a decrease at the highest pH of 8.1. Between pH 5 and 7.9 most elements (Cd, Pb, Cu, Zn and Co) showed a relatively constant recovery, whereas Mn and Ni showed an increase in count rates up to pH 7.1. The recovery of Fe showed a maximum between pH 5.6 and 7.4.

Soil heavy metal pollution resulting from human activities is causing major concern due to its potential risk. In this study, four crop species with different cultivars were planted in 2 levels (heavily and slightly) of heavy metal contaminated soils, and the accumulation of Cu, Zn, Pb, and Cd in the edible parts of the crops were investigated.

The genesis of the Mount Isa Cu-Pb-Zn system, northern Australia, is highly debated. Three metallogenic models have previously been proposed to explain the close spatial relationship between a world-class Cu and Pb-Zn deposit: (1) ca. 1650 Ma syngenetic Pb-Zn mineralisation that has been re-mobilised and overprinted by ca. 1520 …

During the remediation process, the content of free-state P in the soil first increased and then decreased; the early decrease in phosphorus (0–10 days) was attributed to the formation of complexes between M 2+ (Pb, Zn, Ca, etc.) and PO 4 3-, which resulted in the bioavailable content of Pb, Zn, Cu, and Cd decreasing by 81.73 %, 79.58 %, 91. ...

The specific adsorption of divalent Cd, Co, Cu, Pb, and Zn on goethite is measured as a function of pH. For each mole of heavy metal adsorbed approximately two moles of H+ ions are displaced from the interface. Using these results the heavy metal adsorption data are expressed as functions of the solution concentrations of both H+ and metal ions ...
