Chalcopyrite Flotation Process

Apr 01 2014 fig 9 shows chalcopyrite and pyrite recovery from cleaner flotation as a function of collector addition 89 chalcopyrite recovery was achieved in 8 min flotation without additional collector which is higher than that from the flotation of single chalcopyrite shown in fig 3 it suggests that the presence of pyrite enhances chalcopyrite.
