    Bubbles become steadily more and more heavily loaded with attached particles as the bubble passes through the pulp. 8.1.3 Froth phase Particles enter the froth phase when a bubble carrying the particles crosses the pulp-froth interface. The froth phase floats on top of the pulp phase and is formed by the bubbles that break through the

  • Model Predictive Control for Froth Flotation Plants

    Froth flotation Froth flotation is a common method to extract a certain type of mineral from ore while depressing the amount of undesired minerals in the extracted concentrate. It is done by adding certain chemical reagents to selectively rendering the desired mineral hydrophobic. In a flotation cell, air bubbles then lifts the mineral.
