Resumo
Wavelength dispersive X-ray fluorescence spectrometry (WDXRF) is a suitable
technique for the characterization of contaminated mining sites, providing a quick and
reliable screening for areas of significant contamination. This study established and
validated a non-destructive methodology for quantitative simultaneous determination
of major and minor constituents in soil and sediments by WDXRF, which was further
applied to quantify soil and sediment samples from Osamu Utsumi uranium mine
(Caldas, Minas Gerais, Brazil). Elements such as Ce, La, Nd, Mn and U were found
in more concentrated levels in the calcium diuranate deposit (DUCA), whereas Fe and
Al were found at higher levels in the soil samples corresponding to sites where accentuated
leaching processes have occurred. Comparatively, the levels of U and rare-earth
elements were found in significantly higher levels in the sediments retrieved from the
mine’s pit as a result of acid mine drainage. These findings are believed to be useful
as an initial environmental assessment for the decommissioning process of the mine.
