Abstract
Arsenopyrite is separated from a mixture with pyrite by contacting the mixture with a sulfitic agent providing HSO.sub.3.sup.- 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 rich in arsenopyrite.
