Crystallochemical features of iron minerals in bauxite from Vezhayu-Vorykvinskoe deposit (Middle Timan)

The article presents the results of mineralogical and crystal-chemical studies ferriferous types Timan bauxite. The peculiarities of the distribution of Fe2+ and Fe3+ in the structural positions in oxides, oxyhydroxides, and phyllosilicates was discussed. These data are important for improving the technology of processing natural aluminum raw material.
