Coordination Principle of Minerals Flotation

The advent of flotation, with selective interaction of minerals with reagents at its core, has greatly contributed to the development of modern mining. Ever since, there has been continuous research into the mechanism of mineral-reagent interactions, in an effort to design and develop superior reagents. A unique perspective from coordination is presented to illustrate the principles of reagent molecules interacting with metal ions on mineral surface. For the first time, the influence is unveiled of mineral crystal structures and surrounding coordinate atoms on metal ion properties and further on mineral-reagent interactions. The introduction of classical theories for modern chemistry, including orbital hybridization, spin chemistry and orbital symmetry matching, into flotation is realized. Researchers, engineers and graduate students among others in the field of mineral processing may gain new insight into the interaction of mineral surface with flotation reagent.
