Industrial flotation machines can be divided into four classes: 1 mechanical, 2 pneumatic, 3 froth separation, and 4 column. The mechanical machine is clearly the most common type of flotation machine in industrial use today, followed by the rapid growth of the column machine.
Feb 12, 2019& 0183;& 32;Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important appli ion is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.

Applies to: Monohull Boats not amarans, trimarans, or pontoon boats : Mono-hull means that if you can draw a continuous line around the hull at the waterline when the boat is at rest it's a monohull.

The flotation machine IF-30R was designed for mineral processing by flotation. The flotation machine can be used in a pulp flotation process in a wide range of solid parts concentration as well as for enrichment of minerals of high specific gravity. Thanks to the structure of the IF-30R flotation machine it is possible to construct a multi-cell
