Mine Tailings - an overview ScienceDirect Topics

Mill tailings at the Heath Steele mine in New Brunswick contain up to 85 wt.% sulfide minerals (Blowes et al., 1991; Boorman and Watson, 1976). Pore-water pH values as low as 1.0, and concentrations of dissolved SO 4 up to 8.5×10 4 mg L −1 were observed in the shallow pore water of the tailings impoundment ( Figure 12; Blowes et al. , 1991 ).
