With the rapid consumption of independent Cd ore resources, Cd extraction from the Zn ore, Pb-Zn, and Cu-Pb-Zn ores has received increasing attention. In recent decades, due to the low level of mineral processing technology and equipment, most of the symbiotic or associated Cd resources have not been reasonably utilized [ 21 ].
Zn/Cu ratios generally increase with depth, manifesting an enrichment of Cu and Zn in the shallow and the deep levels, respectively. δ 34 S of sulfide minerals varies from − 0.7 to 3.1‰, implying a sulfur composition of magmatic origin. δ 30 Si and δ 18 O of quartz vary from − 0.8 to 0.4‰ and 8.5 to 9.5‰, respectively, similar to ...

Comprehension of the genesis of Pb-Zn ore systems is currently limited by a poor understanding of where these metals are sourced from. Our study of metal mobility during regional metamorphism in the Mt. Lofty Ranges, South Australia, demonstrates that in staurolite-absent siliciclastic metasedimentary rocks, biotite contains >80 % of the …
Jinchanghe is a Zn-Pb-Fe-Cu skarn deposit in the northern Baoshan block, southwestern China. It is a typical distal skarn deposit with orebodies in the Cambrian Hetaoping Formation limestone and calcareous siltstone. The skarn minerals display a vertical zonation with garnet skarn in the lower part and pyroxene skarn in the upper …

1. Introduction. Skarn deposits are typically developed within or adjacent to hypabyssal intrusions of carbonate rocks (Meinert et al., 2005).They represent an important source of Cu–Fe–Au, Pb–Zn–Ag, and W–Sn globally (Einaudi et al., 1981, Meinert, 1992).Vein-type Pb–Zn ± Ag mineralization commonly develops in the distal zones of …
The highest concentrations for Cu, Pb, Zn, Cd, Cr, As and Ni appeared in the range of 60–80 cm depth, while the highest concentration of Hg occurred at the surface soil, which indicated that Cu, Pb, Zn, Cd, Cr, As and Ni had a strong ability to migrate downward, thus posing a potential threat to the deep soil environment, and even …
The elemental concentrations of the resultant solutions show that most Cu, Fe, Pb and Zn precipitated, and up to 120–1140 mg per ... Iron sulfide crystals were observed with sphalerite clusters and anhydrite in the samples where FeCl 2 was ... SXRF images of the thin sections of ore samples from the HYC Zn-Pb deposit. Red: Fe, …
Experimental. Instrumentation. An Agilent 4200 MP-AES was used for the determination of Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Sb, Ti, W, and Zn in digested base metal ores (this …
Iron ore tailing is a major solid waste requiring advanced recycling methods because ore tailing powder is polluting air and water resources. For instance, about 300 million tons of tailings are disposed yearly in 1229 iron ore tailings dams in the Hebei province in China. Iron ore tailings can be recycled as functional materials because these tailings are …
In this study, we prepared a novel iron-based composite (NIC) via a one-step reduction method utilizing refinery sludge (RS) as the reducing agent and iron ore (IO) as the iron source, allowing for the concurrent stabilization of multiple heavy metals (HMs) in soil. The loose, porous structure of NIC provided ample active sites, including Fe 0, CaAl …
