Mining and the Environment: What Happens .
Acid mine drainage is one of the primary sources of miningrelated pollution. Mining activities increase the volume and rate of exposure of sulfurcontaining rocks to air and water, creating sulfuric acid and dissolved iron. This acid runoff dissolves heavy metals such as copper, lead and mercury which leach into ground water aquifers and surface water sources, harming humans and wildlife ...

Recovery of Iron and Aluminum from Acid Mine .
The large volumes of sludge produced through the active treatment of acid mine drainage (AMD) require further processing and final disposal. AMD sludge typically contains a heterogeneous mixture of iron, aluminum, magnesium, and calcium oxides/hydroxides that are of little to no practical value. However, purified iron and aluminum hydroxides have potential commercial value. Based on the ...

"Removal of acidity and metals from acid mine .
One of the biggest environmental impacts of mining is the generation of acid mine drainage (AMD). In the absence of proper postmining management practices, AMD pollution can cause massive environmental damage. Current AMD management practices often fail to meet the expectations of cost, efficiency, and sustainability. The objective of this study was to utilize the metalbinding and acid ...
