A method and apparatus for gas particle formation in liquid media, and its application to gas particle formation in a liquid/slurry in mineral beneficiation apparatus is disclosed. A gas particle formation apparatus comprises an adjustable hollow stem housed within a liquid chamber having a liquid inlet provided in the wall of the casing thereof. The stem is provided with an outwardly flared frusto-conical surface having a circumferential edge defining an annular lip on a head of the adjustable stem. A portion of the surface is adapted to form a thin layer of gas thereon. The adjustable stem is slidably mounted in the casing with the surface of the head received in a circular aperture forming a liquid outlet in the casing, so that an adjustable annular gap is formed between the surface and a convex annular lip of the circular aperture. Gas is delivered through distribution outlets covered by a self-sealing resilient spreader onto the surface portion of the head. In use, both liquid and gas are forced through the gap and as the gas layer escapes from the lip it is broken into gas particles by shear forces. A mineral beneficiation apparatus incorporating the gas particle formation apparatus is also described.
