Muhammad Khan Department of Mining Engineering, Baluchistan University of IT, Engineering and Management Sciences, Pakistan M. Iftikhar Khan Department of Electrical Engineering, University of Engineering and Technology, Peshawar, Pakistan Journal Article 2021 05 04 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 2.85% Cu, 22%  Fe₂O₃, 52.9% SiO₂, and other minor minerals. The optimum grinding time and liberation size of the copper ore have been determined as 30 minutes and +149-105 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 300 (g/t) of the collector potassium amyl xanthate (C6H11KOS2), 250 g/t of pine oil, 250 g/t of a depressant (Na₂SiO₃), conditioning time of 10 minutes for a collector, flotation time of 6 and 10 minutes, and pH of 10 using the froth flotation technique. https://jme.shahroodut.ac.ir/article_2138_e150dceaae20850db323f2b6e9524752.pdf
