| Abstract Scope |
The increasingly low-grade, fine particle size and complex composition of mineral resources require higher efficiency and precision of flotation process. Flotation is one of the core technologies for the efficient utilization of complex low-grade resources, and the flotation reagents (especially collectors) are the scientific basis and the key of flotation technology. Metal ions have a good template effect and can regulate the structure of metal-organic complex to realize directional functional assembly. The metal-organic complex collector with metal ions as functional groups and organic ligands as hydrophobic groups has displayed excellent performance in collecting ability and selectivity, showing a new direction for the development of new flotation reagents. Metal ion-fatty acid and metal ion-hydroxamic acid complexes have made important progress in the flotation process of cassiterite, rutile, ilmenite, and rare earth ore, providing a new approach for the efficient utilization of complex low-grade mineral resources. |
