Pyrite behaviour in a tailings pond - ScienceDirect

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).

Spain has a long mining tradition dating from pre-historic times up to the present day. The cessation of mining activity has generated a large amount of mine wastes, most of which represent geochemical hazards. Mine tailings are watery sludge composed of medium-to-fine-grained material, resulting from grinding and mineral processing (e.g., galena, pyrite, sphalerite, and arsenopyrite).

Arsenopyrite is separated from a mixture with pyrite by contacting the mixture with a sulfitic agent providing HSO 3 - ions at elevated temperature and pH below about 8 for a period sufficient to impart a selective depression property to the arsenopyrite. On addition of a collector the pyrite is rendered floatable, enabling froth flotation to achieve a concentrate rich in pyrite and tailings ...
