dc.description.abstractThe measurement of the magnetic susceptibility and composition of magnetic particles from the natural sand of the Rokan River in Riau Province has been done. Sand samples were taken at 5 different points with a distance of 500 meters from each point. The sample taken at each point has a mass of 1 kg. The samples were dried in the sun ray before separation between magnetic particles and non-magnetic particles using Iron Sand Separator (ISS), this result is called ISS product. The ISS product was milled with different milling tube rotational speeds namely 100, 150 and 200 rpm with iron balls that has 1.5 centimeters in diameter. The product obtained from the ball milling then its magnetic and non magnetic particles was separated using Neodymium Iron Boron (NdFeb) magnet, this result is called ball milling product (BM product). The results of this research indicate that the magnetic susceptibility of ISS and BM product have values (4,601.814-10,930.771) and (6,848.631-33,123.550) . The composition of the elements was identified using X-ray fluorescence (XRF). XRF identification showed magnetic elements such as Fe increased from 13.777% to 27.064%, while non magnetic elements such as Si decreased from 58.401% to 42.920%.en_US
