Rougher flotation of copper minerals in columns ...

2005-6-1  Abstract. In this work, rougher flotation of low grade copper minerals (0.6–0.7% Cu) was tested in column cells at laboratory scale. A negative bias regime was used in order to create a levitating effect on particle–bubble aggregates to promote gross particle flotation. Over 80% recovery was obtained on the flotation of coarse mineral (100% ...

1 Froth Flotation – Fundamental Principles

2009-8-27  1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and
