Introduction. The last 10 years have seen significant advances in the measurement of so-called gas dispersion properties in flotation machines, namely: gas superficial velocity (or simply gas rate) (J g), gas holdup (ε g) and bubble size (diameter, D b).From these can be derived the bubble surface area flux (S b = 6J g /D b, where D b is …
