Water and Mining Conflicts in Peru [PDF]

open access: yesMountain Research and Development, 2008
Impacts on water quality and quantity are among the most contentious aspects of mining projects. Companies insist that the use of modern technologies will ensure environmentally friendly mining practices. However, evidence of the negative environmental impacts of past mining activity causes local and downstream populations to worry that new mining ...

Iron Bacteria in Mine-waters [PDF]

open access: yesNature, 1960
As van Beneden1 has shown, iron bacteria may be obtained from fresh-water by reducing the iron in this water by percolation through a layer of soil. In the thin layer where the effluent oxidizes (presumably ferrous carbonate or bicarbonate to hydrated ferric oxide) the bacteria develop.
