Commodity Zinc is a brittle, whitish metal used in a wide range of industries, most familiarly as a galvanizing material for steel. Known and used for millennia, it was named "zinc" in the early 1500s by Paracelsus, a Swiss physician and philosopher. The name was derived from "zinke," a German word for "fork tooth," referring to the form …
Heavy metal pollution seriously threatens the drinking water safety and ecological environment in karst lead–zinc mines. Fifteen groundwater and surface water samples were collected in a karst lead–zinc mine in Daxin, Chongzuo. Ten heavy metal (Mn, Zn, As, Pb, Cr, Cd, Ni, Co, Cu, and Fe) concentrations were detected. Correlation …

The study area is known for abundant lead-zinc mineralization and igneous activities (Chukwu and Obiora, 2014, Chukwu and Obiora, 2018) and lead-zinc mining has lasted for more than nine decades and presently, mining and quarrying activities are still active in the area. The mines have been grouped into two, namely: Green Field metal …
Purpose The combined contamination of Pb, Zn, Cu, Cd, and As in the soils near lead/zinc mine waste posed a potential threat to the surrounding environment. Mitigation methods are needed to reduce the environmental risk. The aims of this paper were to evaluate the feasibility and efficiency of different forms of phosphates in …
The objectives of this study were to reveal the adaptation of the selected woody plants to mine tailings and the potential use of woody species for the revegetation of mine tailings areas in China. 1 Materials and methods 1.1 Mine tailings and soil Lead and zinc mine tailings were collected from Fuyang City (30 126 ′ N, 119 847 ′ E) and ...
Mining and processing of lead (Pb)/zinc (Zn) ore at the Anvil Range mine occurred near the town of Faro in the Yukon Territory, Canada, for approximately 30 years, beginning in 1968. A study was undertaken to examine whether the mining activities had left a detectable "footprint" on the environment in the way of heavy metal …
The Sidi River, which originates in the upstream lead-zinc mining area, represents the only surface water flow in the study area . The Sidi ... which enhanced the bioavailability and migratory capacity of Mn and had a greater impact on ecological risk than other elements. 3.2. Analysis of the Level of HM Pollution in Soils and Risk Evaluation
1. Introduction. The rapid development of industrialization has produced ever-growing amount of hazardous mine tailings. According to a statistics, more than 5.97 billion tons of mine tailings have been discarded in China till 2011 [1].These solid-state mine tailings, such as lead and zinc mine tailing (LZMT), are frequently rich in toxic heavy …

1. Introduction. Mining activities generate a large amount of tailings that are generally deposited upon the ground surface [1].Tailings usually provide an unfavorable substrate for plant growth because of their low pH, high concentrations of toxic metals, and low nutrient content [2].. At the present study site, one of the largest Pb–Zn mines in …
The former Black Angel lead (Pb)–zinc (Zn) Mine in Maarmorilik in West Greenland (Fig. 1) operated between 1973 and 1990 and the mining activity caused significant contamination mainly of Pb and Zn in the surrounding environment (Asmund, 1992, Larsen et al., 2001, Elberling et al., 2002).During the mining period, …
The mine tailings were collected from the surface layer (0–50 cm) of a typical lead-zinc mine (26°18′33.30″ N, 107°54′14.47″ E), located in Danzhai, Guizhou Province, China, which began mining in 2014 and still in function at present.
