Passive Treatment of Acid-Mine Drainage
Introduction Acidic mine drainage (AMD; also called “acid rock drainage” or “acid drainage”) is an environmental pollutant that impairs water resources in mining regions throughout the world. Where such treatment is required legally, treatment must be efficient and continual. Treatment methods are commonly divided into either “active,” meaning reliance on the addition of alkaline chemicals to n...

متن کاملLong-term Performance of Passive Acid Mine Drainage Treatment Systems
State and federal reclamation programs, mining operators, and citizen-based watershed organizations have constructed hundreds of passive systems in the eastern U.S. over the past 20 years to provide reliable, low cost, low maintenance mine water treatment in remote locations. While performance has been reported for individual systems, there has not been a comprehensive evaluation of the perform...
متن کاملThe microbiology of passive remediation technologies for mine drainage treatment
Water draining abandoned mines or mine sites is often acidic and contains relatively high concentrations of dissolved metals and sulfate. Such water (AMD) arises from the oxidative dissolution of sulfidic minerals, such as iron pyrite (FeS2), exposed by mining activities. As AMD production can occur over a very long time scale, passive remediation systems are becoming increasingly important in ...
متن کاملWastewater treatment polymers identified as the toxic component of a diamond mine effluent.
The Ekati Diamond Mine, located approximately 300 km northeast of Yellowknife in Canada's Northwest Territories, uses mechanical crushing and washing processes to extract diamonds from kimberlite ore. The processing plant's effluent contains kimberlite ore particles (< or =0.5 mm), wastewater, and two wastewater treatment polymers, a cationic polydiallydimethylammonium chloride (DADMAC) polymer...
