3.7.1. Entrainment theory and empirical correlations. There are two mechanisms of entrainment observed in flotation column. First, one is due to the introduction of feed water which contains suspended solid particle, swept into the froth and second is due to entrapment of fine particle (gangue) in rising bubble [ 6 ].
If the latter is the normal procedure it may be due to the mineral not being liberated from the waste well enough to be floated cleanly away from the native rock. When liberation problems are part of the ore's characteristics the designers of the concentrator plant will include a REGRIND MILL in the Basic Flotation Circuit Design of its flow ...

The basic scale-up procedure for flotation plants design consists of using an overall time scale-up factor to compare laboratory and plant at similar flotation recoveries. For example, Thompson (2016) presented a range of flotation scale-up factors of 1.6 to 2.9, where the value for copper sulphide minerals was 2.1.
The Bateman otation mechanism was developed in. S 1993 and is presently marketed by the Bateman Pro-cess Equipment Limited. The BQR series of Bateman cells have a round tank design with cell sizes varying. Figure 8 A schematic diagram of the Bateman flotation cell (courtesy of Bateman Process Equipment, South Africa).
The flotation process is suitable for stop/start operation and has a flow turndown of about 2:1 or greater depending on the design of aeration manifolds. The former is one of its advantages when dealing with a water subject to high algal loadings; a plant can be 'switched in' as and when needed and will give a steady quality treated water ...
