Hybrid Flotation technology. This technology faces the challenges of finer grinding and lower-grade ores. It combines a pneumatic spray-in principle with a column method. The pneumatic component creates very small gas bubbles and inserts high kinetic energy. Feed pulp and gas are mixed inside the mixing chambers of the ejector system before being

Flotation in the mining industry is a very significant separation technique. It is known that fine and ultra-fine particles are difficult to float, leading to losses of valuable minerals, mainly due to their low collision efficiency with bubbles. Flotation of fine particles can be enhanced either by increasing the apparent particle size or by decreasing the bubble size.
