sufficiently proven for them to replace froth flotation. One of the aspects regarding the flotation of ultra-fine coal that has not been conclusively demonstrated is the choice of flotation unit to be employed. Although a number of flotation machines are used around the world, and each claims to be the best, no definite answer is known.

Froth flotation is a physicochemical process that is used to separate fine mineral particles from aqueous suspensions by selective attachment of some types of minerals to air bubbles. Froth flotation is the most important mineral processing technology for the production of valuable mineral concentrates from which metals and minerals are …

 — The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In …

other stages of the flotation process to achieve the maximum efficiency and mineral recovery. Mineral froth created from the flotation cells contains fine particles with a fine dispersion of air bubbles. To move the mineral froth from one flotation cell to another and then to the next process requires pumping.
