Constructed Wetlands for Treating Acid Mine Drainage

2016-5-18  Constructed Wetlands for Treating Acid Mine Drainage. By Kathryn Smith . Introduction . The mining industry has felt the burden of both negative environmental criticism and strong governmental regulations. In the past, mineral extraction and processing has been a source of many contaminants entering our water, soil, and air.

Use of constructed wetlands for acid mine drainage ...

Constructed wetlands have been used for over two decades for the treatment of acid mine drainage (AMD). Through a variety of physical, chemical, biological processes, these wetlands are effective in reducing acidity and removing up to 99% of iron and aluminium from AMD, but they only remove 20-30% of

Acid Mine Drainage Treatment Using Constructed Wetland

2015-3-13  Acid mine drainage samples were collected from Mpumalanga (South Africa) and they were characterized for heavy metals and sulphate concentrations (with pH ranging between 2.6 and 2.7). Three constructed wetlands (all packed similarly) were built and employed to treat acid mine drainage samples with different metal concentrations.

2009-5-1  Four small-scale surface-flow wetlands (Fig. 1) were constructed in spring 2004 at the Kristineberg mine site. All four wetlands were lined with impermeable geotextile placed on the bottom and sides of each basin, on top of which a first 15-cm-thick layer of either unoxidized mine tailings or unpolluted sand was placed.
