Flotation collectors can generally be classified into three categories – nonionic, anionic, or cationic. Nonionic collectors are simple hydrocarbon oils. They can either chemically bond to the mineral surface with high selectivity (chemisorption) or be held on the surface by physical forces (physical absorption). Anionic and cationic collectors are more complex – they include a polar component that selectively attaches to mineral surfaces and a non-polar component that projects out into the solution making the surface hydrophobic.

Arkema custom-develops both anionic and cationic flotation collectors, CustoFloat® and CustoAmine®, for specific ore bodies and process conditions, primarily for the flotation of oxide ores such as phosphate and industrial minerals. We employ a wide range of technologies for anionic and cationic collector formulation that enables us to provide the best collector performance available. Let Arkema work with you to develop and implement a complete, customized flotation collector package to help you succeed.
