The conceptual designs of three new applications for the biogenic &S treatment of metal- containing waters are presented. These include: 1. the treatment of a circumneutral-pH ground water containing Zn and Cd using limestone as an alkalinity source, 2. a two-step treatment process where toxic heavy metals in contaminated ground water are recovered separately from nontoxic metals to lessen disposal costs, and 3. a copper recovery process that may be a low-cost alternative to solvent extraction/electrowinning or cementation for dilute copper leach liquors. Preliminary results of initial field testing are discussed
