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 mineralwater slurry. A finely crushed ore is suspended in water and a blast of air is passed through the suspension.
