The stoichiometric ratios Cu:C, Ni:C, Pb:C, and Zn:C were also calculated. In all sites, a higher Na concentration was found in the 0–10 m from the forest edge. This zone was characterized by increased pH in the O horizon, increased Zn and Ni in the A horizon, and a decreased Pb in the O horizon. There was no clear pattern for the Cu ...
2.1 Copper. The element copper (Latin, cuprum) is primarily obtained from minerals such as cuprite (CuO 2), tenorite (CuO), malachite (Cu 2 CO 3 OH 2), chalcocite (Cu 2 S), covellite (CuS), and bornite (Cu 5 FeS 4).Copper is a natural element found at low contents ranging from 50 to 70 mg kg −1 in soils, with an average of 50 mg kg −1 in the …
The Uragen giant sandstone-hosted Zn–Pb deposit has a proven reserve of 5.90 Mt metals in the southern ore zone and potentially 10 Mt metals for the whole deposit, and orebodies are strictly confined to the bleached clastic rocks of the Lower Cretaceous red beds. The bleaching has been used to guide lead–zinc exploration; however, its nature …
Phytoextraction is a green remediation technology for clean-up contaminated soils. The effect of chelator application including EDTA, EDDS, and citric acid on phytoextraction of Cu, Zn, and Pb into high biomass vetiver (Vetiveria zizaniodides) was investigated in the hydroponic experiment and the pot experiment. In the hydroponic …
The Baoshan block is an important structural unit in the middle-southern segment of the Sanjiang Tethyan Metallogenic Domain (STMD; Fig. 1 a) in SW China (e.g., Hou et al., 2007, Li et al., 2010, Li et al., 2016c, Wang et al., 2015, Wang et al., 2016, Yang et al., 2017a).The subduction of the Tethyan oceanic plate generated abundant granitoids …
The genesis of the giant Ag-Cu-Pb-Zn polymetallic mineralization in the northern Lanping basin, Southwest China, remains controversial. To address the sources of metals, a systematic study on Hg isotope compositions was conducted for the Cu-dominated deposit at Baiyangping and the Pb-Zn-dominated deposits at Fulongchang and Liziping. …

Aims The main aim of this study was to validate the HYDRUS-2D model for the simulation of Cd, Cu, Pb and Zn transport within a soil column and their accumulation by willows. Methods A simulation of metal transport and uptake by willow was implemented using the HYDRUS-2D code. Two scenarios of the column experiment were compared: …

The observed metal adsorption behavior for goethite was better fitted by the CD-MUSIC model (Fig. S9) than for the other Fe oxides, with the lowest V (Y) values for Cu, Pb and Cd. However, the CD-MUSIC model underestimates both Pb and Zn adsorption onto goethite at low pH and low metal loading.
The K d 1 0 0 values observed for sorption by the whole H horizon rank the metals in the order Cr ≈ Pb ≫ Cu ≫ Cd > Zn ≈ Ni, and the K d 1 0 0 values for retention following the desorption stage in the order Cr > Pb > Cu ≫ Cd > Zn > Ni, where ≈ indicates a difference of less than a factor of 1.1 and ≫ a difference of more than a ...
Whilst the initial approach of exploiting relative flotation kinetics using the current RPZC operating conditions did not achieve the desired Cu-Pb selectivity, a …
Wulungu Lake is a vital fishery area in Xinjiang. However, the concentration, enrichment rules, and sources of As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn in the aquatic organisms, have rarely been investigated. The results suggest that the concentrations of As, Ni, Pb, and Zn were higher than those recommended by the national standards for edible …
The Dalong deposit is a new Pb–Zn discovery with a proven reserve of 33,000 t Pb at a grade of 0.90% Pb, 66,000 t Zn with a grade of 3.43% Zn, and 28.5 t Ag at a grade of 5.9 g/t Ag. Recent mapping and mining suggest that the Dalong Pb–Zn deposit might be distal to the Xiangdong W–Sn deposit (416 Geological Team 2013, unpublished internal ...
