Some gas dispersion characteristics of mechanical flotation machines
1.. IntroductionThe 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 …

SELECTION OF MECHANICAL FLOTATION EQUIPMENT
Mechanical flotation cells can be broken down into two broad categories based on how air is introduced to the cell. In a self aspirated flotation cell air is introduced to the slurry, the vacuum created by the rotorusing . In a forced air flotation cell air is generated external to the cell by a low pressure blower,, and pumped down the
