It is therefore essential to study the characteristics of heavy metal in Pb/Zn smelting contaminated soils which provide insights for the environmental behavior of contaminants and the selection of remediation strategies Li et al 2020; Xu et al 2021 Scholars have focused on selected Pb/Zn smelting areas for soil pollution assessment

Estimation of arsenic leaching from Zn Pb mine tailings

Sampling from Zn Pb mine tailings was carried out at the Anguran mine in Jan 2018 and two types of tailings produced from Zn Pb ores by extractive activities were sampled Zinc leaching plant during its process produces two types of tailings which include hot filter cake or cobalt cake S 2 sample and cold filter cake or nickel cake S 1

Revealing the orogenic genesis of Huogeqi Cu Pb Zn

Orogenic type deposit is one of the most important economic deposit types in the world and accounts for large amounts of metal reserves especially gold in the world Goldfarb et al 2005 Chen 2006 Fan et al 2022 The orogenic type deposit is typically hosted in shear zone and the ore fluid associated with the orogenic type deposit shows carbon and reduced

Background Urbanization industrialization and various other anthropogenic and natural activities increase the release of heavy metals HMs into the environment posing a severe threat to nearby flora fauna and humans HMs are toxic non biodegradable silent and subtle killers that alter the soil attributes and threaten plants animals and humans impacting

Accumulation of Pb Zn Cu and Fe in plants and

The case study was represented by a mining area in Hamadan province in the North West part of Iran This study showed that the most of sampled species were able to grow on heavily metal contaminated soils and also were able to accumulate extraordinarily high concentrations of some metals such as Pb Zn Cu and Fe

Immobilization persistence of Cu Cr Pb Zn ions by the

By contrast higher Cu and Zn leachate concentrations were found because they were released by the soil in larger amounts as compared with those of Pb and Cd The differences in the Cu and Zn

Growth of Vetiveria zizanioides and Phragmities australis on Pb/Zn

However the Pb/Zn mine tailings contained extremelyConclusions The use of either manure compost or sewage sludge resulted in decreased pH and DTPA extractable metal ions in the Pb/Zn and Cu mine tailings with a better growth of vetiver and common reed in all treatments except for the use of manure compost in Pb/Zn mine tailings
