Gravity Separation an overview ScienceDirect Topics

The separability of minerals by gravity separation relies on a particles settling rate in a fluid. The terminal velocity of solid spheres settling in a fluid is described by Stokes Law for fine particles (Eq. (15.3)) or Newtons Law for coarse particles ( Eq. (15.4) ). Both these equations include particle density as well as particle size.
