AB The addition of alkaline substances is a technique commonly used to prevent acid production generatedby the weathering of sulphide-rich sludge. In this work, we show the effectiveness of fly ash, a waste ofcoal combustion, as an acid neutralizing residue, by means of the construction of a leaching saturatedcolumn fills with sulphide sludge and fly ash. In addition, in order to understand the behaviour of bothwastes inside the column, a fly ash leaching test (leachates reach a pH>10) and two flow-throughexperiments at pH 9 were carried out to calculate oxidative dissolution rates of pyritic sludge in presenceof the fly ash
