Abstract
Abstract
The correlation between the crystal morphological peculiarities of gibbsite and its position in a bauxite-bearing weathering profile is revealed from the example of the Tsentral’noe deposit of the Chadobets Uplift. The free space favorable for the growth of gibbsite increases from bottom to top in various parts of the profile as a result of infiltration metasomatosis and various physicochemical conditions. The higher the position of the rock, the higher its porosity. The size of the gibbsite crystals thus increases, and their morphology becomes more complex upward through the section. The results of thermal analysis showed that the higher the sizes of the gibbsite crystals, the higher the amount of boehmite forms upon its heating. These conclusions will help the technologists to choose the most feasible reworking scheme of bauxites.
