Entrainment is a process by which fine and ultrafine particles are transferred to the flotation froth from the top of the flotation pulp, and eventually discharge to the concentrate product, even when they are not attached to gas bubbles. Therefore, entrainment can be considered as a two-step process, one at the upper layer of the pulp …

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 in the liquid phase.

Mining - Flotation. One of the most widely used methods of recovering valuable minerals in the mining industry is using froth flotation tanks. Inside these tanks, the ground ore is mixed with water to form a slurry. Hydrophobic materials then separate from hydrophilic materials through the use of chemical additives.
