An experimental investigation of leachate generation predictions of waste from copper sulphide ore processing

Abstract

Word processed copy.Includes bibliographical references.The greatest environmental liability in the mineal processing industry is the prolonged environmental degredation of groundwater and land, resulting from Acid Mine Drainage (AMD) formation from mine wastes due to oxidation of sulphide minerals. AMD enhances the mobilisation of trace and minor metals contained in wastes, therby generating contaminated leachate, which may pollute the ground and surface water. It is imperative to minimise post-closure environmental impacts and liability associated with the long-term generation and dispersion of contaminated leachate from solid mien deposits. Therefore, prediction of the environmental aspects associated with soild mineral waste is essential to their effective management during all phases of a project life cycle including post-closure
