Supersaturated cavitation is the main way of micro/nano-bubble formation in the low-pressure zone of the dissolution air flotation machine with the saturation vapor pressure decreasing (Zhou et al., 1996). There are also a wide range of low-pressure zone in the jet flow machine and the machinery stirring 11 22 11 2 Pu+=+ =rrP u C 2 0 1 im ...
Flotation of fine particle (<37 μm) and ultrafine particle (<8–13 μm) is a key challenge. Feed in flotation consists of wide range of particle size, therefore, flotation column needs to have wider bubble size to target fine as well as coarse size particles [13,14]. So, flotation of fine particles is one of the major challenging tasks.
Novel flotation machines have directly driven significant developments in the aeration system. This paper provides a comprehensive review of the developments and …
