    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

    Copper sulfide ores must be concentrated before they can be economically transported to a smelter. Froth flotation is part of a copper beneficiation process in which finely ground ore is placed in aerated tanks that contain a water-based solution from which a copper-sulfide-rich froth is recovered

    Question: A froth flotation process is used to concentrate copper ore. It is a two-stage process that involves one rougher stage and one cleaner stage. The cleaner tailings return to the rougher flotation. Both stages are nonreactive unit operations that operate at steady-state. The analytical profile of the entire flotation circuit is: -The
