The research aims to synthesis of magnetite nanoparticle from iron sand by mechanomhemical route. The XRF graph of showed the dominant mineral content of the iron sand is SiO2 (36.09%), Fe2O3 (34.015%) and Al2O3 (10.034%). Hereinafter, the Iron oxide nanoparticle synthesized by the ball mill method at different milling time. The XRD graph of samples after milling showed there is no diffraction peak correspond to SiO2, and it only corresponds to Fe3O4, and α-Fe2O3. also showed there is increasing magnetite (Fe3O4) purity as increasing of milling time and homogenous magnetite phase reached at 30 h milling time. The milling time affects the size of crystallites, morphology, and magnetic properties of magnetite nanoparticles. In this paper we will describe the effect of grinding time on these properties in detail. © 2019 Published under licence by IOP Publishing Ltd.
