This is achieved by a combination of the design of the flotation machine (called a flotation cell) and the use of a second class of surfactants known as frothers. In a simplified sense, the role of the flotation machine is twofold: to maintain an agitated (mixed) pulp in the cell, and; to introduce air bubbles into the agitated pulp.

Results show that our flotation machines operate on exceptional grade recovery curves, with respect to coarse and fine particle recovery. The remarkable performance of our machines is related to flotation-favourable hydrodynamics, which produce higher active cell volumes, provide longer residence times, and complement froth removal.

3.4. Effect of cell hydrodynamics on flotation performance. Overall recovery (R O) in a flotation cell is a function of recovery in the collection (R C) and froth (R f) phase, Eq. (4), ( Dobby, 1984 ): (4) R o = R f R c R f R c + 1 - R C. The drivers of recovery are very different in these two phases.
