Acid mine drainage: Prevention, treatment options,
To date, there is no reliable method for the treatment of AMD Therefore, prevention and prediction are the best strategies for handling the mine drainage problem and minimising its environmental impact (Abrosimova et al, 2015, Parviainen et al, 2014, Wei et al, 2014) The recovery and reuse of resources from AMD will require universal and suitable technology2 天前 There are a variety of approaches to preventing and cleaning up acid mine drainage Most of these focus on trying to neutralize the acid, prevent exposure of mine materials to oxygen and flowing/percolating water, or otherwise prevent bacteria from What can be done to prevent or clean up acid mine Active chemical treatment by neutralization has been widely applied by the coal mining industry to prevent the damages caused by acid mine drainage The process involves the addition of alkalineAcid mine drainage: Prevention, treatment options, The diversion of surface and groundwater from acidproducing pyritic waste piles is another important AMD prevention approach Diversion ditches, grout barriers and slurry walls are some of the Acid mine drainage prevention and control options There is no known effective prevention method currently available for AMD The most effective control is to minimize penetration of air and water through the waste pile using a cover, either water or soil, placed over the waste pileAcid mine drainage prevention and control options
Acid mine drainage: Prevention, treatment options,
In this review, the available prevention of acid mine drainage generation, treatment options and their importance in light of the future perspectives are briefly discussed The possible resources to be recovered such as ferric hydroxide, ferrite, rare earth metals, sulphur and sulphuric acid and their economic benefit are discussed The most environmentally effective techniques available for mitigating AMD are internal neutralization methods The chemicals usually used for AMD treatment include limestone, hydrated lime, soda ash, caustic soda, ammonia, calcium peroxide, kiln dust, and fly ash Fig 2: Strategies for Prevention of Acid Mine DrainageAcid Mine Drainage: Sources, Impacts and Prevention ACID MINE DRAINAGE PREVENTION AND CONTROL OPTIONS Nural Kuyucak Golder Associates Ltd 1796 Courtwood Crescent Ottawa, Ontario, Canada K2C 2B5 Phone:+ 1 613 , Fax:+ 1 613 email: nkuyucak@golder ABSTRACT Acid mine drainage (AMD) is one of most significant environmental challenges facing the mining industry worldwideAcid Mine Drainage Prevention and Control Options prevention In this work, we present an explanation and theoretical valuation of the pyrite oxidation process and a compendium on the measures most frequently employed for its prevention and correction Keywords : Acid Mine Drainage, mining, oxidation, pyrite, prevention, pollutionTechniques to correct and prevent acid mine drainage: A Recently, two alternative strategies for the management of AMD and mine tailings are gaining much attention: (1) prevention techniques, and (2) mine waste recycling In this review, recent advances in AMD prevention techniques like oxygen barriers, utilization of bactericides, codisposal and blending, and passivation of sulfide minerals are discussedA review of recent strategies for acid mine drainage
