(2009) 16: 0223-0229 DOI: 10.1007/s11771-009-0038-y Acidophilic bacterial community reflecting pollution level of sulphide mine impacted by acid mine drainage WAN... analysis, it is found that mining pollution greatly impacts the bacterial ecology and makes the habitat type of polluted environments close to acid mine drainage (AMD) ecology. The polluted......
to acidic water generation and water pollution. Therefore, mine waste management is a significant task in mining operations. As known, in strip mining, the overburden is not transported to waste dumps.... Essential engineering issues in mine waste handling are landscape degradation, accounting for ground conditions, closure and rehabilitation planning, possibility of acid water generation, and soil and water......

water can promote metals leaching and removing in tailing medium[1], the heavy metal contents in AMD are enhanced generally, causing the AMD contamination to ecological environment in mine intensified. Surface water percolating through sulfide tailing piles is one of the key factors to produce AMD[2-3], therefore, AMD happens more easily and causes the metal sulfide mine to contaminate more......
of active and abandoned mines as well as processed wastes. Remedial measures to mitigate acid water generation can then be undertaken. 2 Prediction of acid mine drainage Identification of acid... outflow of acidic water from abandoned mines and mineral wastes and occurs naturally within environments containing an abundance of sulfide minerals and microbial activity. When a mine is abandoned......
problems, such as acid mine drainage (AMD), acid rock drainage (ARD) formed by biological and non-biological oxidation of sulfide deposits [31], which pollutes groundwater and surface water, destroys the ecosystem and reduces water consumption for human activities [32]. Mine waste is a source of trace element soil contamination of the environment that may affect local vegetation [33]. Although......
