At present, Australia is the largest exporter of iron ore, with over 90% of the export sourced from hematite deposits in the Pilbara regions of Western Australia. As high grade hematite reserves continue to decline, magnetite provides alternative source of iron ore to sustain current and future production capacity. The major challenges facing processing of magnetite iron ores, especially within arid regions are process water acquisition, excessive slime production and tailings disposal and storage.A recently developed planar magnetic separator (PMS) provides dry processing alternative for magnetite beneficiation. In this study, the effect of selected control parameters (inlet air velocity, magnet disc speed and feed rate) of PMS 300 S2 on its performance have been investigated using a magnetite-quartz model feed. In addition, the performance of the PMS for beneficiating various grind sizes of a selected magnetite ore has been evaluated and compared with that of Davis tube recovery (DTR) tests for the same grind sizes. X-ray fluorescence (XRF), Quantitative X-ray diffraction (QXRD) and Quantitative Evaluation of Minerals by scanning electron microscopy (QEMSCAN) were used to conduct chemical and mineralogical analyses on the test samples.The study showed that, inlet air velocity and magnetic disc speeds have substantial influence on the performance of the PMS. However, feed rate had very little impact on performance of the PMS, except the throughput. The PMS performance compares favourably with DTR as a measure of ultimate Fe recovery as a function of particle grind size. Given the potential of the PMS as a unit operation in magnetite concentrators, its potential as competitor to DTR is discussed. CITATION:Baawuah, E, Kelsey, C, Addai-Mensah, J and Skinner, W, 2019.
