In this work, we focus on the up-gradation of the copper ore of Qilla Saifullah in Pakistan through the froth flotation technique. The chemical analysis of the head copper ore sample reveal the presence of ۲.۸۵% Cu, ۲۲%  Fe۲O۳, ۵۲.۹% SiO۲, and other minor minerals. The optimum grinding time and liberation size of the copper ore have been determined as ۳۰ minutes and +۱۴۹-۱۰۵ µm, respectively, for further processing. The chemical reagents are optimized in order to get a maximum grade and recovery of the copper ore. After comparisons and analysis of the results obtained, it can be concluded that the maximum grade and recovery of the copper ore are achieved at the dosage ۳۰۰ (g/t) of the collector potassium amyl xanthate (C۶H۱۱KOS۲), ۲۵۰ g/t of pine oil, ۲۵۰ g/t of a depressant (Na۲SiO۳), conditioning time of ۱۰ minutes for a collector, flotation time of ۶ and ۱۰ minutes, and pH of ۱۰ using the froth flotation technique.
