    Flotation is a solid liquid separation process. Separation is artificially induced by introducing fine gas bubbles (usually air) into the flotation process system. The gas bubbles become attached to the solid particulates, forming a gas solid aggregate with an overall bulk density less than the density of the liquid; thus, these aggregates rise to the surface of the fluid.
