Eger P author Melchert G author Antonson D author Wagner J author 1993 Three alkaline materials were investigated for their suitability to treat acid mine drainage generated by a research facility located at a remote site in northern Minnesota. The materials investigated were hydrated lime, sodium hydroxide, and magnesium hydroxide. All three reagents were successful at raising pH and removing trace metals from the drainage, but the magnesium hydroxide had the added benefit of producing a maximum pH of approximately 9.5, while the other two reagents resulted in pH values of 12 and greater. In addition, the magnesium hydroxide was available as a high solid content slurry (58%) which simplified application and handling, and which produced the lowest volume of sludge of the materials tested. acid mine drainage acidification alkaline earth metals chemical properties cobalt copper drainage experimental studies hydroxides laboratory studies lime magnesium magnesium hydroxide metals Minnesota nickel northern Minnesota oxides pH pollution porous materials reagents remediation residence time trace metals United States waste disposal zinc 22 Environmental geology Magnesium hydroxide as a treatment for acid mine drainage in northern Minnesota; GeoRef; English; 2002-028930; 10th annual national meeting of the American Society for Surface Mining and Reclamation, Spokane, WA, United States, May 16, 1993 References: 7; illus. incl. 4 tables exported from refbase (https://www.Wolkersdorfer.info/gard/refbase/show.php?record=393), last updated on Thu, 14 Oct 2010 06:38:19 +0200 text Eger_etal1993 CBU @ c.wolke @ 16743 Zamora B A editor Connolly R E editor 1993 monographic book 204 217
