----- ABSTRACT ,Heavy, metals in ,mine, drainage waters of the Roc1 y Mountains can be removed by a two-stage process consisting of (1) neutralization followed by (2) sulfide treatment. The first stage removes ferric and. aluminum hydroxides, and the second (sulfide) stage precipitates the ,heavy, metals that are most objectionable as pollutants, and that are of possible interest for economic recovery.
