Flotation Froth an overview ScienceDirect Topics

For example, froth flotation is a technique commonly used in the mining industry. In this technique, particles of interest are physically separated from a liquid phase as a result of differences in the ability of air bubbles to selectively adhere to the surface of the particles, based upon their hydrophobicity.

Froth Flotation an overview ScienceDirect Topics

The froth flotation technique was originally developed in about 1910 to raise the copper concentrations of the strip-mined ores of Bingham Canyon, near Salt Lake City [9], and was further perfected for the differential separation of lead, zinc, and iron sulfides at Trail, B.C., at about the same time [10]. Flotation technologies are now widely

Flotation Froth an overview ScienceDirect Topics

Froth flotation is a long established technique in mineral processing. Extensive discussion of flotation can be found in the book by Leja (1982); see also recent work by Fecko et al. (2005) and Melo and Laskowski (2006). Basically, particles are either hydrophilic or hydrophobic (Gutierrez-Rodriguez et al., 1984).

Effect of Sodium Oleate Concentration Variations on Froth

The separation of mineral by froth flotation technique depends primarily on thedifference in the wettability of particles.

Meaning that they can be floated directly, but most minerals are
