Progress in China's Beneficiation Technology for Complex Refractory Iron Ore

China's long- time shortage of iron ore resource is an undoubted fact.To rationally exploit and utilize complex refractory iron ore resource is of great importance to the relaxation of the contridiction between the supply and demand of iron ore and the security of the iron and steel industrial economy. The paper reviews the progress in China's benefication technology for complex refractory iron ores. Meanwhile, in light of their property features and the existing problems, the orientation of further research is pointed out.
