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...

This is a communication on the removal of copper(II) ions from a residual mine water using an emulsified liquid membrane (ELM). The membrane was prepared by dissolving the extractant LIX-860 (a salicylaldoxime), used as a mobile carrier, and Span80, a surfactant, in kerosene. The ELM allowed an efficient metal transport from the feed solution towards the strip liquor, in experiments carried out...

In this article, I explore what a critical environmental perspective would look like in Melanesia, where the distinction between nature and culture, and the expectation that science interprets the former in terms of the latter, may not apply. I consider changes in scientific knowledge production and the shift from cultural ecology to political ecology in Melanesian anthropology, including the a...

Sungun Copper Mine is located in an area with a high level of seismic hazard. Most recently, the Ahar-Varzeqan earthquake with a magnitude of 6.2 on Richter scale occurred on August 11, 2012; at a distance about 40 kilometers away from the mine. Nevertheless, the seismic stability of the final pit wall has not been comprehensively reviewed. In this research, the southwestern wall of the final p...
