Abstract: According to the characteristics of the leaching residues of chalcopyrite atmospheric pressure oxidation leaching technics(the copper leaching residues), pure sulphur is reclaimed by using a cyclonic-static microbubble flotation column,and a good separation index which the grade of the pure sulphur concentrate is 47.50% and the recovery is 93.15%.This can not only supply chalcopyrite atmospheric pressure oxidation leaching technics,but also realize the recycle of sulphur resource,so it has good application prospects and economic meaning.
