Froth Flotation Frothers for Mineral Processing
What is Froth Flotation?
Froth flotation is a mineral processing technique used to separate valuable minerals from ore based on differences in surface properties. During flotation, air bubbles attach to hydrophobic mineral particles and carry them to the surface, where they form a froth that can be recovered.
Collectors, frothers, and other flotation reagents work together to create the conditions required for effective mineral separation.
The Role of Frothers in Flotation
Bubble Formation and Froth Stability
Frothers help control bubble size, gas dispersion, and froth stability within the flotation cell. The appropriate froth characteristics help transport valuable mineral particles to the surface while supporting efficient froth removal.
Recovery and Selectivity
Optimizing froth behavior can improve mineral recovery and concentrate grade while reducing the entrainment of unwanted particles. The appropriate frother depends on ore characteristics, flotation chemistry, equipment, and operating conditions.
CustoFroth® Flotation Frothers
Arkema's CustoFroth® frothers are custom-formulated to optimize froth characteristics for a range of mineral processing applications.
Our technical experts evaluate ore characteristics, flotation conditions, and reagent interactions to develop CustoFroth® solutions designed to support:
