Abstract
Based on the properties analysis of the chalcopyrite and the phase analysis of the chalcopyrite, collecting copper from the chalcopyrite by flotation was determined. The effects of grinding fineness, the dosage of dispersant and the dosage of collector were researched. The grinding fineness as 90%, water glass as dispersant 400 g/t and xanthate as collector 170g/t, two- stage scavenging and three-stage cleaning, at this conditions, 22.65% copper was obtained with a recovery of 89.85%. The good mineral processing index was got.
