4 QA you need to know about froth flotation process ...
· In froth flotation plants that process unevenly embedded ore, under the premise of ensuring the recovery rate of roughing, there is a tendency of coarsening of grinding fineness. However, because the coarse particles are relatively heavy, they are not easy to suspend in the flotation cell and have less chance to collide with the air bubbles. In addition, after the coarse particles are attached ...
1 Froth Flotation – Fundamental Principles
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 removed, while the particles that remain completely wetted stay ...
