Frothers | Quadra Chemicals

Frothing, also known as froth flotation, is the process of selectively separating hydrophobic valuable minerals from hydrophilic waste gangue. In its simplest form, froth flotation is a method whereby minerals can be "skimmed" from the surface of "slurry" that is "foamed" with the assistance of specific chemicals, water and air bubbles.

1 Froth Flotation – Fundamental Principles

Froth flotation can be adapted to a broad range of mineral separations, as it is possible to use chemical treatments to selectively alter mineral surfaces so that they have the necessary properties for the separation. It is currently in use for many diverse applications, with a few examples being:

Collectors | Quadra Chemicals

Froth flotation is normally achieved by rendering the precious material hydrophobic. This is done by adding a collector reagent, such as POLYFLOAT™, in the slurry which will change the surface properties of the desired mineral. Air and a chemical frother are then injected into the slurry to carefully control the formation of bubbles.

Physical and chemical interactions in coal flotation

Conventional froth flotation for fine coal cleaning suffers mainly from two problems: (i) a lack of selectivity for fast floating high rank coals due to the flotation of middlings and entrainment of mineral fines in the froth, and (ii) low recoveries for heavily oxidized or low rank coals due to poor adhesion between bubbles and particles.

Flotation Oils for Froth Flotation | ArrMaz

Flotation oils act as co-collectors, extending the collector''s ability to float the desired mineral. They provide strength to the hydrophobic layer. The amount and type of flotation oil used can directly impact the nature of the froth, and thus can control the strength and selectivity of the froth zone.
