Acid mine drainage (AMD) causes several environmental problems in many countries. The use of biological processes with sulphate-reducing bacteria (SRB) has great potential within environmental biotechnology. The aim of this study was to develop a bioremediation system, using a mixed culture of SRB, for the treatment of AMD from São Domingos mine. Sulphate and heavy metals (Fe, Cu and Zn) concen...
Copper-64 shows promise as both a suitable PET imaging and therapeutic radionuclide due to its nuclear characteristics. Stable attachment of radioactive (64)Cu(2+) to targeted imaging probes requires the use of a bifunctional chelator. Sarcophagine (Sar) ligands coordinate the metal ion (64)Cu(2+) within the multiple macrocyclic rings comprising the cage structure, yielding extraordinarily stab...
The Christmas copper mine is in the Banner mining district, Gila County, Arizona. It is 8 miles north of Winkelman and 22 miles south of Globe. The mine was opened in 1905; to the end of 1943 it had produced about 55,340,000 pounds of copper. In 1946 it was operated under lease. The ore is high-lime fluxing ore, required by the smelter at Hayden. The ore produced during 1942 averaged 2.16 perce...
Ground subsidence due to underground mining has posed a constant threat to the safety of surface infrastructure such as motorways, railways, power lines, and telecommunications cables. Traditional monitoring techniques like using levels, total stations and GPS can only measure on a point-by-point basis and hence are costly and time-consuming. Differential interferometric synthetic aperture rada...
soils around mining sites play a significant role in the transport and control of heavy metals in the environment. therefore, understanding the adsorption properties of soil is essential in solving pollution problems. the objective of this paper was to study zn(ii) adsorption onto sarcheshmeh copper mine soils. the adsorption isotherms of zn(ii) were studied. the langmuir isotherm indicated an ...
To investigate potential health risks associated with exposure to metals from an abandoned metal mine, the authors studied people living near an abandoned mine (n=102) and control groups (n=149). Levels of cadmium, copper, arsenic, lead, and zinc were measured in the air, soil, drinking water, and agricultural products. To assess individual exposure, biomarkers of each metal in blood and urine ...
Biological nitrogen fixing is an important source of nitrogen input in the natural ecological restoration of mine wastelands. The diversity of nifH genes in tailings samples under different plant communities in Yangshanchong and Tongguanshan wastelands in Tongling, was analyzed using polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) approach. The nitrogen-fixing micro...
