Abstract

The X-ray fluorescence spectrometry and the MA. BM. 006 reference spectrophotometric methods were used to determine the content of SiO2 (%) in bauxites from different deposits. The treatment of samples prior to the analysis involved the following steps: annealing, melting using the borax method, and the formation of beads. Certified reference bauxite samples were used for the calibration curve. The calibration curve was produced with the correlation coefficient of r =0. 9999 and the standard error of S = 0. 0246. The average residual value between the content of SiO2 determined using the XRF method, and the reference method was 0. 045, with a standard deviation of 0. 068. The XRF method was statistically verified by the F-and t-tests (using the standard sample and the reference method). The values obtained in the tests show that the XRF method yields accurate results and that there are no standard errors.
