    Technical Document Acid Mine Drainage Prediction

    Acid Mine Drainage Prediction compares acid rock drainage factors of waste rock piles and tailings impoundments. In examining this table, it is important to note that diffusion of oxygen into water is slow and, therefore, oxidation of iron sulfide is inhibited until the water level drops, which can occur periodically or seasonally in some cases.

    Chemical stability in tailings with residual sulfide minerals is best managed by maintaining near saturation. Because oxygen has very low mobility in water (i.e., in water, oxygen has ~1/30th the volumetric concentration and 1/10,000th the diffusivity relative to air), there is essentially no sulfide mineral oxidation in watersaturated tailings.
