Abstract
Western, calcium-rich fly ash was used as a tailings amendment in laboratory studies with pyrite, galena, and tailings from a complex sulfide deposit. The base buffering capacity of the fly ash reduced dissolved heavy metal content up to three orders of magnitude. When used in this manner, with a 10 wt-pct fly ash amendment per unit weight of pyrite in the tailings, at least a three order of magnitude reduction in quantity of heavy metals leached through the tailings and into local ground and surface water systems can be expected.
