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:

  • Improved mineral recovery and concentrate grade
  • Controlled bubble size and froth stability
  • Improved flotation selectivity
  • Reduced entrainment of unwanted particles
  • Improved separation efficiency
  • Consistent performance as ore and operating conditions change

Integrated Flotation Reagent Expertise

Frother performance is closely connected to the other reagents used within the flotation circuit. Arkema evaluates frothers as part of the broader flotation reagent program to optimize interactions between collectors, frothers, modifiers, and process conditions.

Our metallurgical experts can conduct laboratory testing and work with customers to optimize frother selection and dosage based on the specific mineral separation challenge.
