• Silicate structure

The surface element distribution, valence and relative density of polyvalent metal cation on anion of nine specie of silicate minerals belonging to five kinds of silicate structure were analyzed by X-ray photoelectron spectrometric. The structure characteristics, element content and state, surface potential, and floatability of minerals are closely related with each other. Because of different structure characteristics of the five kinds of silicate minerals, elements content and valence on dissociated minerals surface are diversities. The surface potential and firm extent combined with collector are discriminative, and the flotation characteristics for every kinds of structures, of silicate minerals in anion collector flotation system are different. The crystal chemistry principle of flotation about many kinds of silicate minerals was researched systemically for the first time.
