The minerals content and its magnetic properties of iron ore from Lhoong mining area, Aceh province were studied. The iron ore was prepared by co-precipitation method. As the results, the main mineral and chemical compositions of samples which were investigated by XRD and XRF analysis tests, showed that the Lhoong iron ore contain Fe 2 O 3 (93.88%) and some minor impurities, such as SiO 2 , MnO, and Al 2 O 3 in varying proportions. Compare to XRD results, it was consistent with XRF, the phase compositions of iron ore are mainly hematite (Fe 2 O 3 ). The XRD revealed that hematite is the major mineral components in the Lhoong iron ores. The magnetic properties of the samples after milling showed there has been increased in the remanent (Br) and coercivity (Hc). The electron microscope identification inform that the particle were agglomerated.
