Research on magnetic characteristic and element content identification from the natural sand of the Rokan River in Riau Province has been done. Sand samples were taken from 5 points with 10 kilograms per point from Rokan River. The samples are dried in the sun before separation between magnetic particles and non-magnetic particles using Iron Sand Separator, this result is called concentrate 1. …
