    Copper Mining and Processing: Processing Copper Ores

    This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps: 1) froth flotation, 2) thickening, 3) smelting, and 4) electrolysis. Following mining, transporting, and crushing to a consistent gravel or golf ball-size, the crushed ore is further processed at a mill

    Explain froth flotation process of copper pyrites

    Copper is extracted from copper pyrites by froth flotation process. Froth flotation method is used to separate particles based on the differences in the ability of air bubbles to selectively attach to specific mineral surfaces in a mineral-water slurry. A finely crushed ore is suspended in water and a blast of air is passed through the suspension

    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
