Simon Nordestgaard - AWITC Early flotation processes relied on oil for flotation rather than bubbles. Hydrophobic mineral constituents of interest were attracted to the oil and recovered. The Bessel brothers were the first to use a bulk oil technique in 1877 for the separation of graphite particles (Elmore 1898 bulk oil process shown). Mechanically agitated flotation
