抄録	Flotation rate of finely ground chalcopyrite (< 5 μm) is low due to the low collision probability between air bubbles and the mineral particles. In this study, effects of emulsifiers in the presence of co-existing minerals and ions on agglomeration-flotation of finely ground chalcopyrite were investigated. Anionic emulsifiers (SDS, KAX) can be used to improve Cu recovery in the agglomeration-flotation of chalcopyrite and quartz because addition of emulsifiers could stabilize the oil-water emulsion and produce smaller oil droplets. When Ca2+ and quartz co-existed, SDS used as emulsifier was consumed by Ca2+ adsorbed on quartz surface, resulting in low Cu recovery due to the coalescence of oil droplets. On the other hand, emulsified oil stabilized by KAX was not affected by the presence of Ca2+ and quartz, so high Cu recovery could be obtained.
