The angular velocity (ω) is often expressed in terms of the rotational speed, N. w = 2πN/60 where w = 60νr/2πr. The centrifugal force, F c, is given by: Fc = mf (2πN/60)2 = 0.01097 mrN2. Centrifugal force is often expressed in the magnitude of the force with respect to the gravitation force (g's):

Harnessing both gravity separation and floatation, as well as dramatically reducing the initial mass to be processed by pre-concentration, Gekko flowsheets increase the grade for downstream intensive processing. This innovative approach maximises the recovery of valuable minerals. It saves vast amounts of operating energy across an entire plant.

Gravity separation relies on different specific gravity of minerals and their relative motion under gravity and drag forces. This chapter describes units, circuits, and strategies that are used to recover gravity-recoverable gold (GRG) from very high-grade gold particles and from sulfidic particles with low-grade gold content.
