    Process Description and Technological Phenomena of A ColumnFeatures of A ColumnAeration The Most Essential Aspect of ColumnsApplication of ColumnsReferencesThe column is fed with ore pulp in its upper third portion and, at the lower section, air is injected at high velocities. This causes the pulp to flow down against a swarm of rising air bubbles. This counter current flow promotes the suspension of particles in the pulp. In addition, the energetic injection of air provides for the generation of small bubbles and promotes the contact of these bubbles with the ore, leading to the collection of hydrophobic particles. The loaded bubbles ascend and form a thick froth layer at the columLive Chat
