Flotation is known as a separation process, based on the introduction of gas bubbles as the transport medium. Suspended particulate matter, being hydrophobic or conditioned to be so, is then attach to the bubbles and moves toward the water solution surface—i.e., contrary to the direction of gravity [ 1, 2 ].

Efficacy of Herbicide Active Ingredients against Aquatic Weeds
As the name implies, many free-floating plants move around with wind or water currents. One strategy is to treat after wind has consolidated plants in one area. This does not always work, however, as wind may push free-floating plants back into stands of emergent vegetation where treatment becomes more difficult.

Jameson cell - Wikipedia
In a conventional flotation column, the void fraction is similarly low, and so the probability of particle-bubble contact is increased by increasing the height of the column to provide greater residence time. [17] Traditionally, the ore slurry and the air are introduced separately to the flotation cell (see Figure 2).

Flotation columns: getting the most from fine ores
Flotation process within a column. Typically, columns are suitable for ores with a particle size bellow 150 µm. Larger particles tend to be too heavy to be kept in suspension. This size limit may vary depending on the ore density. Lighter ores, such as phosphate, are amenable to column flotation at larger particle sizes.

Basic Steps to Fractional Distillation | Understanding Distillation
The basic steps to distillation are:. Add heat to a liquid mixture with two or more main substances; for example, a water and ethanol mixture.; As the liquid heats, components with the lower boiling points will begin to vaporize and rise through the column. In the water/ethanol example, ethanol will boil off first (BP 78° C, compared to water (BP 100° C).
