Based upon microscope observation of ore minerals and analysis of zinc, copper, and strontium …
Most gold mine tailings are composed mainly of industrial sand (i.e., silica) and silica sand is best described as a granular material that is composed of majorly quartz and trace amounts of coal, clay, and other minerals. In some instances, it is referred to as either quartz or industrial sand and is widely applied in many engineering ...

The supergiant Shuangjianzishan (SJS) Ag–Pb–Zn deposit, located in the southern Great Xing'an Range (SGXR), is the largest Ag deposit in China. The SJS deposit can be divided into two ore blocks: the Shuangjianzishan ore block and the Xinglongshan ore block. Given the importance of the Xinglongshan ore block in the SJS deposit, our …
Heavy metals in contaminated ore processing areas present a risk of contamination of waters and life. Therefore, the most mobile fractions of metals, which can be evaluated by chemical extraction, require a special research attention. Classical reports using batchwise extraction methods are debatable in terms of real metal availability …

Mineralization is hosted in carbonaceous and calcareous and, to a lesser extent, siliceous mudstones.
According to the production process of copper concentrate, there are two ways that can reduce Pb and Zn contents in the concentrates: first, depress liberated lead and zinc minerals from the raw ore; second, float lead or …
The Huangshaping deposit represents the largest Pb Zn polymetallic skarn deposit in the southern Hunan district of Nanling Range (South China), which is uniquely characterized by having both Jurassic W–Sn–Pb–Zn and Cu–Pb–Zn skarn mineralization (reserves: 152.9 kt WO 3 @ 0.2 %, 43.2 kt Mo @ 0.06 %, 761.3 kt Pb @ 3.55 %, 1529.1 …
Figure 11.9 shows the locations of non-sulphide Zn ore deposits in the world. Presently, about 85% of Zn production is from ZnS, especially as the flotation is very instrumental in the enrichment of Zn minerals from ZnS sources. ... Brazilian effluent limits for Zn 5.0; Cd and Pb 0.1; Cu 0.5; total Fe 10; Mn and Ni 1.0 mg/L and pH is 6.5–8.5 ...
The Dajing Cu–Sn–Ag–Pb–Zn ore deposit, Inner Mongolia of China, is a fissure-filling hydrothermal ore deposit that occurs within the Upper Permian Linxi group.
Free gold and gold wrapped in sulfides are considered as the object of gold floatation. However, floatation of free gold exhibits more variables in practice. In this study, improving gold recovery of a Pb–Zn sulfide ore from Yunnan Province, China, was investigated. The results show that free gold and auriferous sulfides account for 94.99 …
Ore precipitation in porphyry copper systems is generally characterized by metal zoning (Cu–Mo to Zn–Pb–Ag), which is suggested to be variably related to …
For example, 4 found that the formation of aggregates occurred around plant roots in OM-treated Cu-Pb-Zn tailings. Hence, the colonization of native grasses as pioneer plants would be a useful …
Zn-Pb-Ag mineral deposits are the products of hydrothermal ore-forming systems, which are restricted in time and space. In Australia, these deposits formed during three main periods at ~2.95, 1.69 ...
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 …
2.2 Soil treatments. The P amendments were applied evenly to the soils at a 2:1 molar ratio of P to the sum of Pb, Cu, and Zn. The 2:1 molar ratio of P to metals is much higher than P–metal stoichiometry (P:M = 3:5) for the M 5 (PO 4) 3 OH (M = Pb, Cu, and Zn) precipitate. The large amount of P was used to promote possible precipitation of …
