how does froth flotation work

1 Froth Flotation – Fundamental Principles

Figure 4. If the contact angle is very small, then the bubble does not attach to the surface, while a very large contact angle results in very strong bubble attachment. A contact angle near 90° is sufficient for effective froth flotation in most cases. Figure 4: Contact angle between and air bubble and a solid surface immersed in liquid.

Flotation Froth - an overview ScienceDirect Topics

Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.

Celanese - The chemistry inside innovation

Flotation – A flotation frother – like Methyl Isobutyl Carbinol, 2-Ethyl Hexanol, or terpenic oil – and a “slurry” of fine powder and water are then introduced to a water bath (i.e., flotation cell) which is aerated, creating bubbles. Frothing – A stable froth is formed on the surface of the flotation cell from the aeration.
