Reprocessing of a Southern Chilean Zn Tailing by Flotation ...

The index IP is based on a favorable size range for flotation between 10 µm to 45 µm, which can be considered an unrealistic choice in a general consideration of flotation processes. In the case of experimental data for flotation recovery, IL and IP could be replaced by the normalized recovery of the experimental size and liberation classes.

Froth flotation is a physicochemical separation process. Separation is principally based on differences in surface hydrophobicity. However, particle size and density have a significant impact. Initial flotation patent and application was developed for graphite by the Bessel brothers (1877). Similar to graphite, coal is naturally hydrophobic.
