A practical approach to plant-scale flotation optimization

Frother has two main purposes in flotation. In the pulp phase it reduces bubble size by preventing bubble coalescence, and in the froth phase it increases froth stability (Laskowski, 2004). The effect of frother on bubble size has been well documented, as shown by Grau et al.(2005) and Laskowski (2004).
