AEROPHINE®

2021-12-31 · AEROPHINE Ⓡ promoters are the flotation reagents of choice when treating Cu/Zn, Cu/Pb/Zn and especially Cu/Au/Ag/Pb/Zn ores. These ore types frequently have very high levels of pyrite and other iron sulphides. AEROPHINE Ⓡ promoters are highly recommended over xanthates when selectivity against iron sulphides (pyrite, pyrrhotite and arsenopyrite) is required.
