  • Is lime treatment a good treatment method for acidic mine drainage?
  • Lime treatment is also considered a most applicable technology in terms of economics and efficiency for treating effluents of acidic mine drainage compared to different advanced physical and biological treatment methods.
  • Can quicklime be used as neutralization chemicals in acid mine drainage?
  • Tolonen ET, Sarpola A, Hu T, Ramo J, Lassi U (2014) Acid mine drainage treatment using by-products from quicklime manufacturing as neutralization chemicals. Chemosphere 117:419–424 Sarmiento AM, Olias M, Nieto JM, Cánovas CR, Delgado J (2009) Natural attenuation processes in two water reservoirs receiving acid mine drainage.
  • Can limestone replace lime for neutralization of contaminated AMD?
  • Limestone can replace lime for neutralization of As contaminated AMD. Calcination of limestone (burning at 550 to 1150 °C) results in the formation of quicklime (CaO). Quicklime is rich in Ca and OH − ions after dissolution and can be used to treat AMD by increasing pH and reducing heavy metal contents .
  • How does lime treatment affect acidic wastewater?
  • Lime treatment of acidic wastewaters brings a change in pH (alkalization) resulting in the insolubility of these toxic metals that leads to the formation of minuscule particles due to precipitation reactions.
