Introduction Acid rock drainage (ARD) is currently a significant problem within the mining and minerals processing sector of South Africa. The ideal approach to handling of sulphidic waste rock is to prevent the potential for generation of acid rock drainage (ARD) through the removal of the sulphide phase before its disposal, thus avoiding the need for long-term mitigation strategies.
