Therefore, research on the beneficiation of above ores is extremely significant. This article reviews the present situation and technical problems on utilization of the lean iron ores in China over the past years. Moreover, the major progress in the technology and equipment is summarized. Efficient separation as well as energy saving is still the core in utilization of the ore. Emphasis is placed on different processes developed in upgrading the ore grade to plants and realizing the comprehensive utilization problems.
