Rapid analysis with energy-dispersive X-ray fluorescence spectrometry for bauxite investigation on the Mambilla Plateau, North Eastern Nigeria

Mineralogical and Physical–Chemical Characterization of a Bauxite Ore from Lages, Santa Catarina, Brazil, for Refractory Production

“…However, the goethite is not fully crystallized because the presence of aluminum from the aegirine phase is still existent, probably as a relict, which can be seen in regions 3 and 4 ( Figure 12). The aluminum peak slightly higher than the iron peak seems to confirm this fact (Idris, Funtua, and Umar 2004;Feng and Yapp 2008). Table 3 presents the semi-quantitative chemical composition of regions 4, 5, and 6 from Figure 9.…”

A technique for determination of metallic impurities in Al2O3 matrix by EDXRF

“…Greenaway et al did a comprehensive minor and trace elemental characterisation in Jamaican hillside and catchment bauxites using multivariate techniques that included WDXRF, EDXRF and instrumental neutron activation analysis (INAA) [19]. Similar EDXRF experiments on alumina collected from Mambilla Plateau, North Eastern Nigeria were also reported by Idris et al [20]. Peschel et al have described earlier the use of XRF based technique for alumina analysis [21].…”

Energy dispersive X-Ray fluorescence determination of minor and major elements in soils of Mambilla Plateau Northeastern Nigeria

“…Calcium concentration in all the samples ranged from 0.18 to 0.48%, with elemental mean values of 0.48% ± 0.04, 0.33% ± 1.33 and 0.32% ± 0.02 at E, N, and S locations appropriately. However, Idris et al (2004) revealed 48.08, 18.90, 1.26, 7.71 and 1.93% for Al 2 O 3 , SiO 2 , Ti 2 O, and K 2 O in bauxite analysis of Mambilla samples. The Spectrum Analytical (2016) reported acidic soils to have less calcium.…”

“…The location N 2 gave the highest concentration of Fe 29.14% and mean values of Fe at locations E (19.00% ± 2.70), N (23.16% ± 3.10) and S (9.81% ± 1.40), respectively. While Idris et al (2004) reported 7.71% Fe 2 O 3. This study result agrees with iron being the fourth most abundant element on earth crust present in form of silicate minerals or iron oxides and hydroxides (Schulte, 2004); in addition, resulting in red and yellow colours due to iron concentration of the soil (Isaac et al, 2018;Schulte, 2004;Havlin et al, 2003).…”

“…The inductive neutron activation analysis (INAA) method has been adopted by Tenpe and Parwate (2015), Njing`a et al 2013, and Ene et al (2009), X-ray fluorescence (XRF) by Towett et al (2015), and total X-ray fluorescence (TXRF) by . The energy dispersive X-ray fluorescence (EDXRF) was determined by Sudhakaran et al 2018, Thomas et al (2016) and Idris et al (2004), wave dispersive X-ray fluorescence (WDXRF) by Grosheva et al (2007), and proton induced X-ray emission/ion beam analysis (PIXE/IBA) by Mahmud et al 2015. These are few among many studies that in turn have made available data and significant contributions to the soil literature for proper use and sustainability from the global threatening environmental degradation.…”
