Abstract: Taking the ore-bearing rock series of Bauxite in southeast wing of Chepan syncline of Chongqing as research object，the main content and trace elements of 41 samples were analyzed by adopting the inductively coupled plasma emission spectroscopy method and the distribution characteristics of scandium was discussed.The research results showed that the grade variation coefficient of scandium in bauxite and the rock types is 50，which are unevenly distributed.Then content of scandium in iron clay rock of seam floor is higher，following by the clay rock roof.In general，the content of scandium has no relationship with the ore-body thickness.Scandium often replaces iron and magnesium and other elements as isomorphous form.There has no correlation between scandium content and Al，w(Al₂O₃)/w(SiO₂)，SiO₂.According to the content of Sc in ore bearing rock series in bauxite in southeast wing of Chepan syncline，most of them reach the comprehensive utilization grade.The preliminary beneficiation experiment results show that the impurities can be removed from the preliminary enrichment so as to obtain high purity scandium oxide，and recovery of scandium is basically higher than 95% by adopting the process of high iron bauxite roasting，chemical pre-desilication，Bayer process with flotation desulfurization of high sulfur bauxite，flotation desilication and Bayer process.Therefore，the associated scandium can be recovered during production of bauxite.
