Effect of Frothers on Bubble Size and Foam Stability in
The objective of this project was to compare the effect of a selective flotation frother (MIBC) and powerful frothers (DEMPH and DF1012) on bubble size and foamability in water and in brine. In water, the bubble size is clearly reduced by flotation frothers which prevent bubbles from coalescing.
Robust Products for a Strong Stable Froth Flotation Process
The FrothPro product line works above and below the surface by adjusting the surface tension. Below the surface, the frothers create smaller, more stable bubbles to maximize mineral attachment. Above the surface, the frothers create a protective layer to prevent coalescence and maintain mobility.

Frothers an overview ScienceDirect Topics
In Mineral Processing Design and Operations (Second Edition), 2016. 18.2.2 Frothers. Frothers are surfactants, usually organic heteropolar compounds such as alcohols or polyglycol ethers. Due to the heteropolar nature, the frother adsorbs at the air/water interface
Introduction to Mineral Processing
Frothers are liquids that produce the froth or foam on which the flotation process depends. The froth resembles soap suds and provides the physical separation between the mineral(s) floated and the pulp containing the waste. The froth must be strong enough to support the weight of the mineral floated and yet not be tenacious and nonflowing.

Fundamental properties of flotation frothers and their
Froth flotation process requires the use of frothers. These important flotation agents are commonly characterized as either selective or powerful and are chosen following general guidelines and verification by laboratory and/or pilot plant tests.

Frothers amp; Froth Flotation ArrMaz
During the flotation process, frothers help create the ideal hydrodynamic conditions (such as bubble size and gas holdup) required within the pulp in the flotation cell. They generate froth that is stable enough to hold collected minerals on top of the pulp, mobile enough for removal, and decays quickly to assist with downstream operations.

A good frother should have negligible collecting power, and also produce a froth which is just stable enough to facilitate transfer of floated mineral from the cell surface to the collecting launder. Frothers are generally heteropolar surfaceactive organic reagents, capable of

The froth flotation process commonly requires the use of a multitude of chemical reagents including collectors, frothers, surface modifiers, and pHregulators. Frothers play an essential role in determining the bubble size distribution as well as the stability and mobility of the froth phase [1,2]. The fundamental properties of frothers have

Froth Flotation was initially developed to separate sulfide minerals . such as chalcopyrite from gangue. Collectors and frothers are added to a slurry to attach selected minerals to air bubbles to float them to the surface to be collected as a concentrate. Many sulfide and oxide. minerals can be floated.
