In this second part of the Review on foam and froth flotation, many other aspects of the flotation process are examined, referring mainly to the separation of particulate matter. The effect of...

The schematic representation of a foam fractionation column shows a launder foam collection unit that is typical of the foam collection method used in froth flotation. The foam reaches the top of the column and discharges over a weir into a launder vessel around the periphery of the column with a bottom slanted to a discharge tube. Depending on the stability and rheology of the foam at the top of the column, the gas disengages from the foam

The use of froth in flotation is twofold. Firstly, froth is used to convey the mineral laden bubbles from the froth-pulp interface to the concentrate launder. Secondly, froth is used to remove entrained hydrophilic particles by the gravity drainage of water back to the pulp (Figure 13). The froth cleaning process can be improved by applying spraying (wash) water upon the surface or inside the upper layer of the froth. The spraying increases the volume of water draining through the froth
Froth flotation is a long established technique in mineral processing. Extensive discussion of flotation can be found in the book by Leja (1982); see also recent work by Fecko et al. (2005) and Melo and Laskowski (2006). Basically, particles are either hydrophilic or hydrophobic (Gutierrez-Rodriguez et
