Physiological Effects of Mining Contaminants on Algae with Special Reference to Heavy Metal Toxicity
The process of mining affects all the components of environment and ecology. resulting in different types of pollution problems like soil, surface and ground water pollution. Acid Mine Drainage (AMD) and mine spoil dumps may contain an elevated amount of Heavy metals. Physiological effect of heavy metal toxicity on algal species like Chlorella vulgaris, Scenedesmusbijugatus, Oscillatoriaamphibi...
lichen species (hypogymnia physodes and evernia prunastri) were used for biomonitoring thepossible air pollution with heavy metals in the vicinity of copper mine in the eastern part of the republic ofmacedonia. the contents of 18 elements were analysed by icp-aes and etaas techniques. for dataprocessing basic statistical methods and multivariate exploratory (factor and cluster analysis) techniq...
Impact of copper mine tailings (stamp sand) on survival and development of aquatic organisms near Gay,
In the Cheshmeh-Bid district of Khajeh-Jamali ophiolitic massifs (Southern Iran), mantle peridotites are intruded by abundant pyroxenite dykes. A few these dykes remarkable for occurrence native copper associated with development a metasomatic reaction zone. The progressively reacted, from their margins towards center, an amphibole + antigorite selvage, followed centimeter-thick clinopyroxene a...
Cheshmeh Gaz (Nasim) copper deposit is located in northwest of Bardaskan, Khorasan Razavi province. Geology of the area is consist of andesite, basalt, nummulitic limestone, and marl with gypsum intercalations Eocene in age, Pliocene conglomerate, and Quaternary sediments. Mineralization has been formed in andesites and contact between andesitic units and limestone as stratabound with dissemina...
Several industrial pollution sources at the territory of the Republic of Macedonia, were studied, one Pb-Zn mine with mill, one copper mine with mill and copper leaching facility, as well as one former Pb-Zn smelting facility near the city of Veles and one Fe-Ni smelting facility near the city of Kavadarci. The concentrations of heavy metals at Veles hot-spot were in the range: 20÷1823 mg kg1Pb...
The microbial composition of acid streamers (macroscopic biofilms) in acidic, metal-rich waters in two locations (an abandoned copper mine and a chalybeate spa) in north Wales was studied using cultivation-based and biomolecular techniques. Known chemolithotrophic and heterotrophic acidophiles were readily isolated from disrupted streamers, but they accounted for only <1 to 7% of the total micr...
Sponsored by Defense Threat Reduction Agency Contract DSWA01-98-C-0176 The Mine The cooperating mine was the Morenci Mine operated by Phelps-Dodge in SE Arizona. The scale of the operation is illustrated below. The mine produces over 25% of all US copper. Three to five blasts are detonated daily. During July and August, 31% of the events in the USGS Mine Event List were from this mine. Regional...
This paper introduces an integrated design for realtime plant modeling at a copper mine, using Support Vector Machines (SVM), Neural Networks, and new technologies such as Machine-to-Machine (M2M) and Cloud Computing with an Android client. This solution was designed for a plant inside a copper mine which cannot tolerate interruption and for which their in situ modeling, in real time, is an ess...
