متن کاملPassive 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 کاملPassive Biological Treatment of Acid Mine Drainage: Challenges of the 21 Century
Acid mine drainage (AMD), characterized by a low pH and high concentrations of sulphates and heavy metals, is a disquieting problem for the Canadian mineral industry and other industries elsewhere in the world. Traditional active systems, including lime neutralization, become costly in time or inapplicable in remote regions. Research has recently focussed on passive biological systems that have...
