Study of the possibility of selective flotation of quartz-feldspar ore of Quang Nam deposit (Vietnam)

The article presents the results of study possibility selective flotation main minerals quartz-feldspar ore Quang Nam deposit (Vietnam) - mica and feldspars in presence cationic collector ArmacT, order to remove iron-bearing isolation into high quality concentrates. adsorption regularities ArmacT on mineral surfaces were studied. Results zeta potential measurements showed that at pH = 2 functional group has a significantly higher affinity for compared with both feldspar quartz. Analysis Fourier transform infrared spectra highest intensity is observed 2, while sorption quartz was 5. reducing iron content during obtaining concentrate from samples investigated. Experiments performed under laboratory conditions DENVER machine allowed us determine following optimal minerals, which obtain highquality concentrates:– рН regulator concentration (H2SO4O) – 2000 g/t; (sodium oleate ArmacT) 300 g/t 200 g/t, respectively;– time 3 min.
