all steps of a mining project generally disturb the environment'soriginal condition during construction. therefore, it is crucial toimplement an appropriate mine reclamation plan throughout all mineplanning stages from sustainable and environmental point of view.planting the suitable plant species in each step of any reclamationplan and each area is one of the necessities in this respect.select...
A cross-comparison of six strains isolated from two different regions, Chambishi copper mine (Zambia, Africa) and Dexing copper mine (China, Asia), was conducted to study the leaching efficiency of low grade copper ores. The strains belong to the three major species often encountered in bioleaching of copper sulfide ores under mesophilic conditions: Acidithiobacillus ferrooxidans, Acidithiobaci...
To construct copper heap leaching structures, a stepped heap of ore is placed over an isolated sloping surface and then washed with sulphuric acid. The isolated bed of such a heap consists of some natural and geosynthetic layers. Shear strength parameters between these layers are low, so they form the possible sliding surfaces of the heaps. Economic and environmental considerations call for stu...
The present work was planned to evaluate the phytoextraction of metal mine tailings, Sarcheshmeh copper mine, SE of Iran, by the endemic plant species Medicago sativa L. (Alfalfa). In this pot experiment, we investigated the effects of seven amendments on the growth of alfalfa and uptaking metals from the mine tailings and stream sediment of tailing dam surface. The mean metal concentrations in...
Background: Workers in different occupational positions experience significant Cu exposures, however, Cu toxicity has not been fully studied as compared to other heavy metals. In the present study, hematological and hepatic alterations have been investigated among copper mine workers. Materials and Methods: This descriptive study was conducted in a copper mine in west of Iran, on 402 copper mi...
معدن مس دره زار در استان کرمان،80 کیلومتری شمال شرق سیرجان، 19 کیلومتری شرق بخش پاریز، در فاصله 10 تا 12 کیلومتری جنوب معدن مس سرچشمه قرار دارد. این معدن دارای ذخیره 282 میلیون تن با عیار 38/0 درصد مس با کالکوپیریت بعنوان کانی اصلی مس می باشد که 88 درصد ذخیره آن مربوط به زون هایپوژن و 12 درصد مربوط به زون سوپرژن است. در این تحقیق با تهیه نمونه نماینده از سنگ معدن مس دره زار و انجام مطالعات کا...
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...
the recovery process of selenium from iranian sar-cheshmeh copper anode slimes employing hydrometallurgical methods has been investigated. the copper anode slimes are made up of those components of the anodes, which are not soluble in the electrolyte. they contain varying quantities of precious metals like gold, silver, selenium and tellurium. they are being extracted as a by product in the co...
acid mine drainage (amd) containing high concentrations of iron and sulphate, low ph and variableconcentrations of heavy metals leads to many environmental problems. the concentrations of cu and mnare high in the amd of the sarcheshmeh porphyry copper mine, kerman province, south of iran. in thisstudy, the bio-remediation of cu and mn ions from acid mine drainage was investigated using two nati...
