Gravity Separation - ScienceDirect

2016-1-1 · The separability of minerals by gravity separation relies on a particle’s settling rate in a fluid. The terminal velocity of solid spheres settling in a fluid is described by Stokes’ Law for fine particles (Equation ) or Newton’s Law for coarse particles (Equation ). Both these equations include particle density as well as particle size.
