Celanese - The chemistry inside innovation

Unlocking Minerals from Ore – The Value of Froth Flotation. Froth flotation is an important concentration process that selectively separates hydrophobic valuable minerals from hydrophilic waste gangue. In its simplest form, froth flotation is a method where minerals can be “skimmed” from the surface of “slurry” that is “foamed” with the assistance of specific chemicals, water ...

Froth-based modeling and control of a batch flotation

10-01-2016  Froth flotation is a physiochemical process for separating valuable and unwanted gangue minerals (Napier-Munn and Wills 2011). Effective flotation-system control is difficult to achieve, owing to the nonlinear, dynamic nature of the process (Bergh and Yianatos, 2011, Bonifazi et al., 2002, Shean and Cilliers, 2011).
