“…The results were initially evaluated against dates obtained by U-Pb TIMS 364 and further favourable comparisons were made with data obtained by EPMA and LA-MC-ICP-MS. 365 A popular application of energy dispersive XRF (EDXRF) has been the analysis of ore concentrates. [366][367][368] Savichev and Sorokin 245 proposed a simplified method of fundamental parameters in the analysis of soils and rocks by EDXRF. This involved a calibration based on correction of the observed line intensity only for sample absorption; the best accuracy was achieved for major element oxides when potassium was used as the reference element.…”

“…Considering this, several researchers previously applied X-ray fluorescence (XRF) spectrometry and prompt gamma–neutron activation analysis system in the analysis of metal concentrations in ore concentrates. 1,3–8 XRF spectrometry was suggested as a viable option for determining the concentration of major, minor, and trace elements in ore concentrates using proper calibration methods. By comparison, inductively coupled plasma–mass spectrometry is an alternate approach for the determination of minor and trace elements in ore concentrates.…”

As a technique capable of rapid, nondestructive, and multi-elemental analysis, portable X-ray fluorescence (pXRF) has applications to mineral exploration, environmental evaluation, and archaeological analysis. However, few applications have been conducted in the smelting industry especially when analyzing the metal concentration in ore concentrate samples. This research analyzed the effectiveness of using pXRF in determining the metal concentration in Fe concentrate. For this proof of concept study, Fe ore samples dominated by Fe and Si were collected from the Northeastern University Mineral Processing Laboratory (Shenyang, China) and directly analyzed using pXRF, laboratory-based XRF, and titration methods. The compactness (density) of the ore concentrate was found to have very little effect on pXRF readings. The pXRF readings for Fe and Si were comparative to laboratory-based XRF results. Based on the strong correlations between the pXRF and XRF results (Fe: R2 > 0.99, Si: R2 > 0.96), linear calibrations were adopted to improve the accuracy of pXRF readings. Linear regression equations derived from the relations between XRF results and pXRF results of 21 Fe ore concentrate samples were used to calibrate the pXRF, and then validation was performed on five additional samples. Results from this preliminary study suggest that ordinary least squares (OLS) regression improves the accuracy dramatically, especially for Fe with relative errors (REs) decreasing to 0.03%–3.27% from 4.26%–8.32%. Consequently, pXRF shows strong promise for rapid, quantitative analysis of Fe concentration in Fe ore concentrate. Based on the results obtained in this study, a larger, more comprehensive study is warranted to confirm the results obtained.

“…Some techniques for elemental analysis of fly ash, ores, and similar materials are used, as atomic absorption spectrometry, [15,16] neutron activation analysis (NAA), [17,18] inductively coupled plasma atomic emission spectrometry (ICP-AES), [19,20] X-ray fluorescense (XRF) technique, [5,[21][22][23][24] and energy dispersive spectrometry (EDS) technique. [25,26] Energy dispersive spectrometry (EDS) technique is more practical, cheaper, and faster than others.…”

Fly ash samples collected from main thermal power plants of Turkey such as Sivas-Kangal, Ç ay|rhan, Tavs°anly´, Tunc¸bilek, Soma-B, Seyito¨mer, Yatag˘an were analyzed by elemental SEM-EDS and their secondary electron images were taken. With EDS analyses, some elements such as Si, Ca, Mg, Na, K, S, Fe, Al, Zn, Nb, Ti, and Pu were determined on fly ash samples. The ranging amounts of major elements for different plants were discussed. The radioactive element is observed only for two locations.
