The process of froth flotation entails crushing and
grinding the raw ore to a fine size. After mixing these
fine particles with water, the slurry (pulp) was fed in the
flotation cells, while the mixture and introduced air were
agitated continuously to form a large number of bubbles
[9] (Fig.1). By adding chemicals, valuable minerals were
made hydrophobic in order to attach to the air bubbles
that rose up to the froth layer on the top of slurry, where
valuable minerals were collected.
