Abstract This paper deals with the behaviour in a tailings pond of the residues produced during the flotation of a complex sulphide ore. The composition of the tailing was essentially pyrite (63.4%) with minor amounts of Cu, Pb and Zn sulphides (1.4, 0.5 and 0.8, respectively). In addition, sulphite ion and other thiosalts were present in the liquid phase.
