Particle-bubble attachment in flotation froths ScienceDirect

During flotation, hydrophobic particles detach from the bubbles in the froth phase due to bubble coalescence, bubble bursting and froth overloading. While some detached particles drain back to the pulp phase, a fraction may selectively re-attach to the bubbles rising in the froth. This should result in grade profiles through the froth.

Mineral Attachment and Bubble Bursting in Flotation Froths

Mineral froth flotation is used to separate particles of valuable mineral from its associated gangue. It involves the selective separation of the hydrophobic particles from the slurry into the froth. As air is blown into the slurry, the hydrophobic particles attach to the air bubbles, while the waste particles remain in suspension. While the froth...

Effect of flotation frothers on bubble size and foam

Mar 01, 2002· In a flotation process, frothers are utilized to enhance generation of fine bubbles and to stabilize the froth. According to Leja–Schulman's penetration theory, the interaction of frothers with a collector in the moment of the particle-to-bubble attachment is a vital step in the particle–bubble

Role of frother on bubble production and behaviour in

Nov 01, 2008· 1. Introduction. The addition of frother is nearly universal in mineral flotation plants. Among the exceptions are operations where high salt levels in the process water can replace the two prime functions of the frother, namely to act in concert with the gas dispersion device to control (reduce) bubble size, and to provide froth-building capacity.

Froth flotation KRÜSS Scientific

The formation of small foam bubbles is required for the flotation process. These lead to a large internal foam surface area and therefore to an increased adsorption capacity for the solid to be separated. Our optical method for measuring time and height-dependent foam structure provides important information for optimizing bubble size.
