Acid mine drainage (AMD) has been a detrimental by-product of coal mining for many years. At present, acid mine drainage continues to pose a potential problem in some areas, despite improved prediction and prevention techniques. Acid Mine Drainage Research Acid mine drainage (AMD) has been the subject of intensive research since the 's File Size: 89KB. mineral processing and includes acid rock drainage (ARD), neutral and alkaline waters, mineral processing waters and residual waters. MIW can contain metals, metalloids and other constituents in concentrations above regulatory standards. MIW affects o miles of receiving waters in the United States, primarily by acidic drainage

Mammel, K.J. Loos, T.J. Fink, T.A. Lewis, and B.C. Mulinix ( May ). RC (Final) not available: Presentation. The electrochemical recovery of metals from water has been practiced in the form of electrometallurgy for a long time.
The first recorded example was in the midth century in Europe which involved the electrochemical recovery of copper from cupriferous mine waters. The electrochemical mechanism for metal recovery is based on cathodic Cited by: Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines.
Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually. Water is an integral part of mining operations and is used in all aspects including exploration, mining, mineral processing, and closure.
Mines obtain their water from a variety of sources including allocation from the bulk water infrastructure (third-party water), groundwater, and surface water (rainfall and runoff), but the mines in arid regions rely heavily on groundwater of variable Author: R.
Thiruvenkatachari, S. It involved the recovery of copper from cupriferous mine water electrochemically. During the past two and half centuries, electrochemical technologies have grown into such areas as energy storage, chemical synthesis, metal production, surface treatment, etc.
The electrochemical mechanism for metal recovery is very by: Acid mine drainage (AMD), which has long been a significant environmental problem, results from the microbial oxidation of iron pyrite in the presence of water and air, affording an acidic solution that contains toxic metal ions.
Electrochemical treatment of AMD offers possible advantages in terms of operating costs and the opportunity to recover metals, Cited by: The goal of this project was to obtain the necessary experimental information required to determine the feasibility of an electrodialytic ion exchange (EDIX) cell-based metal recovery system as applied to acid mine drainage (AMD), and.
by-products from acid mine drainage is a promising treatment approach from a technical, economical and environmental point of view. Detailed laboratory investigations should follow to study the recovery of various by-products, to develop a treatment process flowsheet and to evaluate the economical and environmental Size: KB.
Electrochemical water treatment systems are emerging as a potential solution because they reduce both hardness and TDS without the use of salt at a relatively high efficiency rate. The technology goes by several names: continuous electrolytic deionization, capacitive deionization or electrically regenerated ion exchange.
Wastewater treatment is a process used to remove contaminants from wastewater or sewage and convert it into an effluent that can be returned to the water cycle with minimum impact on the environment, or directly reused. The latter is called water reclamation because treated wastewater can be used for other purposes.
The treatment process takes place in a wastewater treatment. Remediation of Acidic Mine Water. Waters draining from abandoned metal mines and mine wastes are often acidic (pH Cited by: EPA/ May ELECTROCHEMICAL REMOVAL OF HEAVY METALS FROM ACID MINE DRAINAGE By Nicholas B.

Passive (wetland) treatment of waters drainingabandoned and derelict mine sites has a numberof detractions. Detailed knowledge of many ofthe fundamental processes that dictate theperformance and longevity of constructedsystems is currently very limited and thereforemore research effort is needed before passivetreatment becomes an “off-the-shelf” Cited by: AbstractAn electrochemical treatment process using an external power supply connected to an electrical circuit consisting of oxidising electrodes immersed in an acid mine drainage (AMD) source water oers a simple, eﬃcient, eective, chemical-free active treatment for removal of iron.
