Ecological restoration alters microbial communities in mine tailings profiles.
Ecological restoration of mine tailings have impact on soil physiochemical properties and microbial communities. The surface soil has been a primary concern in the past decades, however it remains poorly understood about the adaptive response of microbial communities along the profile during ecological restoration of the tailings. In this study, microbial communities along a 60-cm profile were ...
متن کاملReview of Ecological Restoration Technology for Mine Tailings in China
Article history: Received: 11.11.2014. Received in revised form: 4.2.2015. Accepted: 6.2.2015. The disposal of mine tailings is identified as one source of an environmental impact finally resulting in a typically degraded ecosystem. It can easily cause air and water pollution and is a source of man-made mudslides with high-potential socioeconomic-energy impacts. Pollution control and ecological...
متن کاملMicrobial communities in acid mine drainage.
The dissolution of sulfide minerals such as pyrite (FeS2), arsenopyrite (FeAsS), chalcopyrite (CuFeS2), sphalerite (ZnS), and marcasite (FeS2) yields hot, sulfuric acid-rich solutions that contain high concentrations of toxic metals. In locations where access of oxidants to sulfide mineral surfaces is increased by mining, the resulting acid mine drainage (AMD) may contaminate surrounding ecosys...
متن کاملDiversity of free-living nitrogen-fixing microorganisms in wastelands of copper mine tailings during the process of natural ecological restoration.
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...
متن کاملPreventing acid mine drainage from mine tailings
Mining activity always has high impact on its surroundings, being waste deposition the cause of multiple and complex problems to the environment. One of them is Acid Mine Drainage (AMD), causing acid water percolation through large areas in the mine site. Portugal was a prosper tungsten producer from the beginning of the XX century, having its apogee during World War II. Nowadays there are mill...
