Keywords flotation, process optimization, Taguchi orthogonal array, ANOVA. 1. Introduction Froth flotation is widely used for separating base metal sulphide minerals in complex ores. One of the major challenges faced by the flotation of these ores is the ever varying grade and mineralogy as the ore is exploited (Kabuda et. al., 2011).
Besides heterocoagulation, particle size is very critical for optimum molybdenite flotation. Coarse molybdenite particles (120 200 mesh) float extremely rapidly and completely without being influenced by heterocoagulation. The flotation of fine molybdenite particles (minus 200 mesh) is sensitive to particle size and heterocoagulation.

The mill speed is determined by a simple relationship Vc critical velocity Vc 42.3/(D molino)1/2 Vc 42.3/Square root of the diameter in meters.
Flotation is normally accustomed to clean the 28 mesh size fraction, although spirals and high media cyclones have demostrated success in cleaning right down to 100 mesh coal feed. Spirals are often used for middling sizes (10 mesh to 60 mesh). Coal Flotation Plant The flotation of proper coal from the host could be in tanks, columns and cells.
