This technology has acclaimed importance as a versatile process for

Dynamic froth stability of copper flotation tailings ...

Abstract In this work, dynamic froth stability is used for the first time to investigate the flotation behaviour of copper tailings. Reprocessing of material from tailings dams is not only environmentally desirable, but also increasingly economically feasible as head grades can be high compared to new deposits. Flotation tailings, however, usually contain a large proportion of fine (10–50 μ ...

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.
