| Abstract: | Acid mine drainage (AMD) and fly ash from thermal power plants both pose substantial environmental problems in India. Fly ash from the Talcher super thermal power plant was converted into zeolite and used in a column to treat AMD from the abandoned Gorbi opencast mines (Singrauli coalfields, NCL). The pH of the mine water increased, and 100 % of the total hardness, Ca hardness, Mg hardness, Mn, Zn, Pb, Cd, Ni, and acidity were removed, along with 99 % of the Fe and 90 % of the Cu. |
