Flotation Machine - an overview | ScienceDirect Topics

The Davcra cell (Figure 12.81) was developed in the 1960s and is considered to be the first high-intensity machine.The cell could be thought of as a column or reactor/separator device. Air and feed slurry are contacted and injected into the tank through a cyclone-type dispersion nozzle, the energy of the jet of pulp being dissipated against a vertical baffle.

Apr 25, 2014· Abstract. Froth flotation is a widely used process of particle separation exploiting differences in surface properties. It is important to point out that overall flotation performance (grade and recovery) is a consequence of the quality and quantity of the solid particles collected from the pulp phase, transported into the froth phase, and surviving as bubble-particle aggregates into the overflow.
