Moys (1978) conducted experiments in a flotation cell to investigate the effect of various mechanisms (true flotation, entrainment and drainage) on the gradients of mineral concentration in the froth. Results showed that the entrainment mechanism was related to the state of solids suspension in the flotation cell and the drainage rate in the froth.
