The HydroFloatTM laboratory cell is a clear plastic column with an internal diameter of 14 cm. Water and air are introduced to the cell through a circular manifold located in the lower portion of the cell. The cell has a conical bottom which directs slurry to a pinch valve that controls the discharge of tailings.

In the conventional flotation cell, the detachment of particles from the bubbles due to turbulence is the main reason for the decline in the coarse particle recovery (De et al., 2007, Fuerstenau et al., 2007).However, turbulence is imperative in the flotation cell to bring about bubble particle collision, keep particles in suspension, and disperse air flow into fine bubbles.
