Abstract

Bauxite is the primary ore for aluminum extraction. In order to assess the quality of bauxite, it is important to determine not only the content of Al2O3 but the content of Fe2O3 as well. Determining the composition of bauxite is very important from the aspect of determining the quality of bauxite. Therefore, it is important to use a method that is fast, accurate, and precise. In this paper the results of the comparison of two methods are presented. Bauxites of different deposits were analysed for their content of Fe2O3 (mass %), using the X-ray fluorescence spectrometry and reference spectrophotometric method MA. B. M.018. The samples were annealed prior to the process, and beads were prepared by pressing for the purpose of the analysis. Certified reference samples of bauxite were used for producing a calibration curve. The equation for calculating the content of Fe2O3 (mass %) in the samples of bauxite was derived from the calibration curve, which was obtained with the coefficient of correlation r = 0.9989 and the standard deviation S = 3.4420. The XRF method was statistically verified by the F-test and t-test (using the standard sample of the bauxite and the reference method). The values obtained from the mentioned tests showed that the XRF method was imprecise and inaccurate for determination of iron oxide in bauxite, when the samples was prepared by pressing.
