The geochemical behavior of zinc, lead and copper from sulfidic tailings in a mine site with potential to generate acidic drainage (pyrite (55%) and sphalerite (2%)) is reported in this paper. The mining area is divided in two zones, considering the topographic location of sampling points with respect to the tailings pile: (a) outer zone, out of the probable influence of acid mine drainage (AMD...

The Lubin underground mine, is one of three mining divisions in the Lubin-Glogow Copper District in Lower Silesia province (Poland). It is the source of polymetallic ore that is rich in copper, silver and several heavy metals. Black shale is also significantly enriched in fossil organic matter in the form of long-chain hydrocarbons, polycyclic aromatic hydrocarbons, organic acids, esters, thiop...

A 5-yr study was conducted to measure the rates of recovery of fish and invertebrate communities following reclamation of a watershed impacted by an abandoned coal surface mine in Southwest Missouri. Quarterly monitoring of water quality information (pH, conductivity, and alkalinity) was conducted at 10 sites. Annual monitoring of biological (benthic invertebrate and fish community structure), ...

in this study, the biosynthesis of gold nanoparticles by penicillium chrysogenum, isolated from ahar copper mine, was investigated. the gold nanoparticles were synthesized by reducing the aqueous gold ions using the culture supernatant of the filamentous fungi. the uv–vis spectrum displayed a characteristic peak at 532 nm that is very specific for gold nanoparticles. the xrd spectrum confirmed ...

in equilibrium with metallothionein at pH 7.4 after 48 hours. We are currently reexamining copper binding to normal metallothionein and metallothionein from subjects with hepatolenticular degeneration under different experimental conditions. If, as Scheinberg suggests, copper is bound to metallothionein in the cuprous form, our interpretation of the data is indeed incorrect, and I will take ful...

Several coastal rocky shores in northern Chile have been affected by the discharges of copper mine tailings. The present study aims to analyze the chemical speciation of heavy metals in relation to the diversity of sessile species in the rocky intertidal benthic community on the northern Chilean coast, which is influenced by the presence of copper mine tailings. In particular, the chemical form...

Although Dahongshan Copper Mine, a subsidiary of Chinalco Co., Ltd., has large production scale, it is still non-ferrous metal underground mine with low mechanization and labor efficiency due to its early production. In recent years, mines have carried out number beneficial scientific explorations practices on safety management. According their own actuality, they combined They done meticulousl...
