Evaluation of Frother Types for Improved Flotation ...

A laboratory study was conducted to evaluate and compare the effectiveness of nine different frother types when used in a three-phase, continuously operating froth flotation system. The frothers included several that are commonly used in the industry (e.g., MIBC, 2EH, and F-1) as well as unique frother types (e.g., F-3). The tests were conducted in a 5-cm diameter laboratory flotation column ...

The potential of acoustic sound to improve flotation ...

2020-8-1  A common approach to improving froth stability and thus the flotation rate is by increasing frother dosage, but this approach sometimes comes with the overfrothing issue (Laskowski et al., 2007, Stevenson and Lambert, 2012). Therefore, an alternative to improve froth stability is needed to complement the current practice.
