Determine Froth Flotation Kinetics

 · Kinetic Models: The kinetic approach is certainly the oldest and most traditionally used. It postulates that the flotation rate follows a rate equation similar to those utilized to describe homogeneous kinetics. Its foundation is based on the well known analogy existing between bubble-particle and molecule-molecule collisions.
