Title Passive-treatment of acid rock drainage: what is the potential bottom line? Type Journal Article
Year 1995 Publication Min. Eng. Abbreviated Journal
Volume 47 Issue 3 Pages 250-253
Keywords mining acid drainage passive treatment system 3 Geology
Abstract Passive-treatment systems that mitigate acid-rock drainage from coal mines have been operating since the mid-1980s. Large systems at metal mines are being contemplated. A typical man-made passive-treatment-system can mimic a natural wetland by employing the same geochemical principles. Passive-treatment systems, however, are engineered to optimize the biogeochemical processes occurring in a natural wetland ecosystem. The passive-treatment methodology holds promise over chemical neutralization because large volumes of sludge are not generated. Metals may be precipitated as oxides, sulfides or carbonates in the passive-treatment system substrate. The key goal of a passive-treatment system is the long-term immobilization of metals in the substrate materials. The passive-treatment technique may not be applicable in all mine-drainage situations. -from Author

Title Mitigation of water contamination at the historic Ferris-Haggarty Mine, Wyoming Type Journal Article
Year 1999 Publication Min. Eng. Abbreviated Journal
Volume 51 Issue 8 Pages 49-53
Keywords Reclamation and conservation Groundwater problems and environmental effects geological abstracts: environmental geology (72 14 1) geomechanics abstracts: excavations (77 10 10) abandoned mine copper hydrogeology mine drainage United States Wyoming Ferris Haggarty Mine
Abstract An historic underground copper mine in Wyoming is discharging neutral but copper-laden water into a pristine creek. The EPA-deferred site qualifies for reclamation by the Wyoming Abandoned Mine Land (AML) program. The cleanup goal is to restore the discharge so that the creek can eventually support a trout fishery. Hydrological and geochemical investigations underground have suggested two sources of mine water: one clean and the other containing copper. Results of bench- and pilot-scale tests support the viability of using low-cost passive treatment techniques to reduce copper concentrations in the near-freezing mine discharge.
