Remediation of acid mine drainage
Environmental Chemistry Letters, 2019Acid mine drainage induced by the mining industry causes environmental and economic issues. Acid mine drainage contains mainly metals such as Fe, Al, Cu, Ca, Mg, Mn and Zn. Preventing the formation of acid mine drainage has not been found feasible. As a consequence, remediation treatments have been developed during the last years to remove metals and ...

Acid mine drainage remediation options: a review
Science of the Total Environment, 2005Acid mine drainage (AMD) causes environmental pollution that affects many countries having historic or current mining industries. Preventing the formation or the migration of AMD from its source is generally considered to be the preferable option, although this is not feasible in many locations, and in such cases, it is necessary to collect, treat, and

Leaching of heavy metals in acid mine drainage
Waste Management and Research, 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.

The Geographical Journal, 1995
The drainage of waters from abandoned coal and metal mines is often acidic with an elevated heavy metal content. Interaction between this acid mine drainage and the environment can cause gross pollution. Whilst temporary engineered remediation can lessen the impact, complete amelioration is only possible using active and/or passive treatment systems ...

Journal of Environmental Science and Health . Part A: Environmental Science and Engineering and Toxicology, 1991
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.

Acid mine drainage as a coagulant
Minerals Engineering, 1992Abstract Chemical analysis of two AMD samples from a Canadian source showed the presence of cationic species (Al+++, Ca++, Cu++, Mg++, Mn++) in the concentration range 200–1,000 mg/L, and relatively high Fe+++ and Zn++ concentrations (1,500–4,500 mg/L).

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.
