Abstract

Recent changes in the Red Dog water discharge permit reduced the allowable selenium discharge concentration to 6.0 ug/L. When these changes were introduced, the selenium concentration in the treated effluent was 9 ug/L. Over the last two years, this concentration has decreased to 4.5 ug/L. The release and subsequent selenium reactions in the mill circuit were investigated using mill and concentrator surveys. Designed flotation experiments were also carried out to determine the factors responsible for selenium release. The fate of selenium in the tailings impoundment was investigated using thermodynamic tailings pond simulations. Laboratory tests were conducted to determine the long term release rates. A water and sediment sampling campaign from different areas in the tailings impoundment was conducted.
