Traditional ground based monitoring of mining activities are no longer acceptable or sometimes sufficient in terms of assessing sustainable business practices. Remote sensing is increasingly influencing the changing social and management processes of mineral extractions. This study focuses on the application of hyperspectral remote sensing to monitor water and vegetation pollutions at the Dexin...

Background: The workers of mines, during a working day, are exposed to stress and psychological pressure that certainly affect the efficiency of their work. This study aimed to determine the level of stress, anxiety, and depression in workers of one copper mine in Kerman Province, Iran. Materials and Methods: In this cross-sectional study, 250 workers of the operation unit of one copper mine...

In this study, two species of algae from two different areas impacted by acid mine drainage (AMD) were analyzed for metal ion accumulation. The two species of algae collected were Klebsormidium and Entransia. Both algal species are located in an area of high metal ion concentrations and low pH (ranging from 2.28 to 2.89). The study assessed the concentration of iron, manganese, zinc, copper and...

Knowledge of the probable origin and behaviour of arsenic certainly gives valuable insights into the potential for transfer in the environment and of the risks involved in mining sites. Sequential extraction analyses are common experiments often used to study the origin and behaviour of potentially toxic elements. The method, however, presents some deficiencies, including labor-intensive proced...

Mining activity produces metal sulfide wastes particularly pyrite which remain in the mine long after operations cease. When water percolates through a mine where oxygen is present, a series of chemical reactions occur which produce extremely low pH and high concentrations of toxic sulfate and metal ions. This toxic leachate can cause severe aquatic habitat degradation downstream of the mine. T...

Noise emissions are a significant environmental impact caused by the mining industry in all technological phases of surface mining, mineral processing, and waste disposal. This paper presents role noise assessment control large-scale operations. Mine planning develops model operations, ore excavation, dumping scheduling processing rates, including spatial distribution activities. Such level min...

The mining and use of copper by prehistoric people on Michigan's Keweenaw Peninsula is one of the oldest examples of metalworking. We analyzed the concentration of lead, titanium, magnesium, iron, and organic matter in sediment cores recovered from three lakes located near mine pits to investigate the timing, location, and magnitude of ancient copper mining pollution. Lead concentrations were n...

Copper toxicity to the freshwater algae Selenastrum capricornutum and Chlorella sp. and the marine algae Phaeodactylum tricornutum and Dunaliella tertiolecta was investigated using different parameters measured by flow cytometry: cell division rate inhibition, chlorophyll a fluorescence, cell size (i.e., light-scattering), and enzyme activity. These parameters were assessed regarding their usef...
