Flotation Collectors for Industrial Minerals
How Flotation Collectors Work
Collector selection plays an important role in determining flotation performance. Depending on the mineral surface chemistry and desired separation, collectors can be classified as anionic, cationic, or nonionic.
Anionic and cationic collectors contain a polar component that interacts with mineral surfaces and a non-polar component that promotes hydrophobicity. This enables selected mineral particles to attach to air bubbles and be separated during the froth flotation process.
Selecting the appropriate collector chemistry, dosage, and flotation conditions is essential for achieving efficient mineral separation.
