Preparation of iron oxide nanoparticles from natural sand of Ampalu Pariaman beach, West Sumatra has been done using ball milling method. The structural and morphological properties and magnetic susceptibility were measured using X-Ray Diffractometer (XRD), Scanning Electron Microscopy (SEM) and PS-2162 Pasco probe, respectively. The sand was first processed using an Irond Sand Separator (I…
