Froth flotation is a physico-chemical 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.
