Abstract: X-ray fluorescence is a non-destructive compositional analysis technique, which allows the measurement in field, requiring minimum to no sample preparation. This mini-review presents the physical principles and examples of applications of XRF for the analysis in this study X-ray Fluoresce Spectroscopy (XRF).Technique is widely used for the determination of both major and trace elements in three iron oxides (Hematite, Magnetite and Kagnatite) such asFe, Mn, Cu, As, Pb, and Rb, at law and different concentration. Moseleys Law was conducted to determine the concepts strength, and the value of the Rydberg constantR_for each sample (Hematite, Magnetite and Kagnatite) was determined to be2.23310^ (-18) J, 2.14455910^ (-18) Jand 2.32945110^ (-18) Jrespectively.
