Kinetic theory of interacting particles in dilute suspensions of mineral waste
- 31 Downloads
A kinetic theory of interacting spherical particles in dilute suspension is developed which results in a Boltzmann transport equation. This equation is solved in the relaxation time approximation to calculate the settling velocity of fine particulates in the steady state. The theory is applied to the suspended Jamaican bauxite waste and kaolinite particles. The experimental settling velocity compares well with the calculated values at low concentrations. This treatment can form the basis for a more rigorous theory applicable to denser systems and non-spherical particulates.
