Abstract

The production of acidic mine waters containing high concentrations of sulphate and metals is of great environmental concern. One method for neutralizing acidity and removing metals from leachate waters is by stimulating sulphate reduction in a treatment system, thereby producing alkalinity and hydrogen sulphide. Dissolved metals and hydrogen sulphide may then precipitate as metal sulphides. Laboratory and field studies have been conducted for the evaluation of the removal processes in a groundwater treatment system, in which both inorganic and organic materials have been used to neutralize acidity and to promote the growth of sulphate reducing bacteria (SRB).
