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
