The Geochemistry of Acid Mine Drainage
2014Mining and mineral processing generates large volumes of waste, including waste rock, mill tailings, and mineral refinery wastes. The oxidation of sulfide minerals in the materials can result in the release of acidic water containing high concentrations of dissolved metals.

Microfluidic Screening to Study Acid Mine Drainage
Environmental Science & Technology, 2020Acid mine drainage (AMD) is the most significant environmental pollution problem associated with the mining industry. Case-specific testing is widely applied and established in the mining and consulting businesses for AMD prediction, and any improvements in its efficiency, while reducing its environmental impact, are of utmost societal importance.

Abstract One of the serious problem faced by the mining industry is the disposal of acid mine drainage in view of it's harmful effects on receiving water bodies. Studies were conducted at Churcha underground mines of Colleries of South Eastern Coal Fields (Coal India Ltd) on the acidic mine waters with a view to evolve effective treatment system.

Flotation in Acid Mine Drainage Control: Beneficiation of Concentrate
Canadian Metallurgical Quarterly, 1997This paper is focused on recovering residual sulfide minerals by flotation from the tailing of the Pyhäsalmi Cu-Zn mine in Finland. The tailing contains 4–8% sulfide sulfur and according to the static test it is strongly acid producing, having a low ratio of neutralization potential to acid production potential (NP/AP < 1).

Leaching of heavy metals in acid mine drainage
Waste Management & Research: The Journal for a Sustainable Circular Economy, 2006Acid mine drainage is one of the most serious environmental problems that the coal and metal mining industry is currently facing. The generation of low pH drainage enhances the dissolution of heavy metals in water. The samples used in this research originated from three pits at mine dumps.

Sequestration of Phosphorus by Acid Mine Drainage Floc
Journal of Environmental Quality, 2003ABSTRACTSolubilization and transport of phosphorus (P) to the water environment is a critical environmental issue. Flocs resulting from neutralizing acid mine drainage (AMD) were tested as a possible low‐cost amendment to reduce the loss of soluble P from agricultural fields and animal wastewater.

Bioremediation of acid mine drainage in a uranium deposit
Hydrometallurgy, 2007Acid drainage waters generated in the uranium deposit Curilo, Bulgaria, were treated by means of different passive systems such as natural and constructed wetlands, alkalizing limestone drains, permeable reactive multibarriers and a rock filter, used separately or in different combinations.

Pre-Mine Prediction of Acid Mine Drainage
1988The uncontrolled release of acid mine drainage (AMD) is perhaps the most serious impact mining can have on the environment. The cumulative length of streams worldwide affected by acid mine drainage is not known, but over 7000 km of streams in the eastern United States are seriously affected by acid drainage from coal mines (Kim et al. 1982).

Acidic Mine Drainage: The Rate-Determining Step
Science, 1970The rate-determining step in the oxidation of iron pyrite and the formation of acidity in streams associated with coal and copper mines is the oxidation of ferrous iron. Effective pollution abatement necessitates controlling this reaction.
