how to craft mineral flotation tecnhnic

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

    Froth Drainage. The use of froth in flotation is twofold. First, froth is used to convey the mineral-laden bubbles from the froth–pulp interface to the concentrate launder. Second, froth is used to remove entrained hydrophilic particles by the gravity drainage of water back to the pulp ( Figure 13)

    Aug 31, 2020 Lowering flotation pulp density is usually used to reduce fine and ultrafine particle entrainment in mineral flotation plants, especially in cleaner flotation. In addition, the basic principle of most methods for decreasing mechanical entrainment is to reduce water recovery and promote the drainage of gangue particles from the froth zone to the
