Flotation - Mineral Processing & Metallurgy
The bubbles of air, sucked or blown into the pulp in the flotation machines, become coated with mineral and rise to the surface where they collect in the form of a mineralized froth. This primary concentrate, in which the bulk of the mineral is collected, continuously flows or is scraped over the lip of the machine into a collecting launder.

Three commercial oils commonly used for the froth flotation of fine coal were fractionally distilled in a high-efficiency laboratory column. When the individual fractions were tested for flotative power on Gresford and Bedlington fine coals, little variation was found, except that components boiling at temperatures below 180° or above 280° had less power than those in the middle range.

TECHNICAL NOTES 9 FLOTATION - mineraltech.com
A more or less stable layer of froth is maintained on the surface of the slurry. Particles that are attached to bubbles will tend to remain attached at air-water interfaces when the bubble enters the froth layer. Particles that are retained in the froth are recovered at the lip of the froth weir at the edge of the flotation cell.
