The research of determination of the oxide mineral contents of the Tegal Lenga Beach iron sand by using XRD has been done. Iron sand samples were taken from the top layer of the Tegal Lenga Beach sand. The three sand samples were taken from three different places which were separated at a distance of 15 m one another. The separation process is carried out using magnetic separation method. The characterization methods include mass fraction and X-ray diffraction (XRD). It obtained that the average mass fraction of the Tegal Lenga Beach iron sand is 54.71%. The minerals oxide contained are magnesium diiron (III) oxide (Mg Fe2 O4 and iron iron (III) titanium aluminum magnesium vanadium manganese silicon oxide (Fe4.42 Fe5.245 Ti4.72 Al0.7 Mg0.4 Cr0.3 V0.15) (Fe7.82 Mn0.114Si0.06) O32). The main oxide mineral compound is Magnesioferrite (MgFe2O4) oxide mineral of 51.34%
