Abstract: A hematite ore from Australia are characterized by high iron，sliming easily and fine disseminated，hitherto regarded as being difficult to obtain qualified iron concentrate with conventional mineral processing process.Deep reduction-magnetic separation technology on the ore was carried out using coal as reductant in order to provide technical mechanisms for exploitation and utilization of the ore.The results showed that reduction temperature and time were the main factors that influence the deep reduction efficiency; iron powder with Fe content of 78.13% and recovery of 98.19% were obtained via dealing clinker，which are from deep reduction with excess multiple in coal blending of 2.0，at reduction temperature of 1 250 ℃ for 50 min，bed thickness of 30 mm，with grinding(about 80% passing 200 mesh) and one low intensity magnetic separation(107 kA/m）process.The process of deep reduction-low intensity magnetic separation technology is an effective way in exploitation of the ore.
