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 ...

Dynamic froth stability of copper flotation tailings ...
2018-8-1 A laboratory scale, unstirred flotation column was used for the dynamic froth stability experiments in a modified Bikerman test.This set up is similar to the systems used in a variety of other studies (Ip et al., 1999, Cilek and Karaca, 2015, Li et al., 2017).The column was 157 cm tall with graduations on the front wall and a square cross sectional area of 139.2 cm 2.

60 Centuries of Copper: The Flotation Process
2018-9-24 In the case of copper minerals, the particles adhere to this froth, which is separated, whereas the great bulk of the useless material sinks to the bottom of the tanks. By varying the chemical conditions within the cells different results can be obtained, thereby making flotation highly selective in skilled hands.

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.
