Method Of Control Of Acid Drainage From Exposed Pyritic Materials
US Patent:
4314966, Feb 9, 1982
Filed:
Sep 12, 1980
Appl. No.:
6/186898
Inventors:
Robert Kleinmann - Bethel Park PA
International Classification:
A61L 222
US Classification:
422 28
Abstract:
Acid drainage from exposed pyritic material such as coal mine tailings is reduced through the controlled application of anionic detergents which inhibit the bacterium Thiobacillus ferrooxidans. The controlled application of anionic detergent comprises an initial application of anionic detergent in sufficient quantities to satisfy the adsorptive capacity of clay or clay-sized particles overlying the pyritic material coupled with the application of an anionic detergent inhibitor of Thiobacillus ferrooxidans from a slow release matrix containing the inhibitor. The two applications are to intercept infiltrating water up-gradient of the pyritic material or strata. The amount of matrix employed is calculated in accordance with a described formula. The method can be used to reduce acidity in drainage from pyritic mine tailings, coal mines, coal refuse piles and construction sites at which acid drainage is a problem. Acid drainage is also reduced by the mere controlled application of specific anionic detergents which inhibit the bacterium Thiobacillus ferrooxidans utilizing a detergent-containing matrix which provides detergent concentrations of greater than 10 ppm and preferably greater than 25 ppm in the infiltrating water.
