Crystal structure behaviour of iron sand (Magnetite/Fe₃O₄) extracted using mechanical alloying method (grinding time variation)

Iron sand (Magnetite/Fe₂O₃) extracted using the mechanical alloying method with time variations 2 minutes (sample A/C662), 4 minutes (sample B/C690) and 6 minutes (sample C/C691) have been conducted. The result XRD pattern shows that there is proof that milling time affects the crystallinity of iron sand. The sharper peak and increased peak diffraction of iron sand by different milling times show that the milling time can cause an increase in the crystallite. The sharp peak (the best crystalline) is the sample milling at 6 minutes (sample C/691). The phase of iron sand contains hematite, magnetic and silica according to the plane of indices miller.
