froth flotation rule of thumb

CPC Definition B03D FLOTATION; DIFFERENTIAL

Froth flotation (or simply flotation) is a physico-chemical separation process that utilises the effect that different materials normally show also differences in surface properties (e.g. surface tension), for separating a mixture of materials into its fractions.

:: Selecting Flotation Cells: How Many and min-eng.com

The issue of froth handling must be considered during the initial test work. Circuit designers need information on froth removal rate versus flotation time and observations of froth stability if they are to select the correct launder options. The four "new" rules of thumb: 1. Use at least 5 cells for rougher/scavenger applications. 2. Less is Best.
