Beschreibung
Zusammenfassung:	The invention discloses an acid-base self-sufficient sulfur-oxygen mixed ore recovery process which can realize effective separation of sulphide ore (copper sulphide or zinc sulfide concentrate) and oxidized ore (flotation tailings) through a flotation process aiming at sulfur-oxygen mixed copper ore or zinc ore with different grades and different oxidation degrees. Therefore, efficient recovery of the valuable element copper or zinc of the sulfur-oxygen mixed copper ore or zinc ore is further realized. Besides, acid and alkali are generated through bipolar membrane electrodialysis, acid and alkali self-supply can be achieved, acid and alkali consumed by other acid-consuming substances or removed in the process can be prepared only by purchasing a small amount of sodium sulfate or sodium chloride, and the method is particularly suitable for areas where acid and alkali control is strict or areas where acid and alkali transportation is difficult. 本发明公开了一种酸碱自给的硫氧混合矿回收工艺，可以针对不同品位及不同氧化程度的硫氧混合铜矿或锌矿，通过浮选工艺实现硫化矿(硫化铜或
