In the present experimental study the stabilisation of sulphidic wastes exhibitingstrong acid generation potential, with the addition of 5-15% w/w treated or untreated red mud(RM) was investigated in laboratory columns which were subjected to weekly wet-dry cyclesusing distilled water as leaching agent. The experimental results over a period of 200 daysindicate the potential of RM to stabilise hazardous sulphidic wastes, substantially improve thequality of the produced leachates and minimise the risk of surface- and groundwatercontamination. Use of RM for waste stabilisation reduces disposal costs and associatedenvironmental impacts and may also improve the quality of the amended substrates prior to thedirect development of a vegetative cover on waste disposal sites
