A Review on the Beneficiation of Ultra-Lean Iron Ores

Abstract:

Nowadays, the demand of Chinese market for iron ores exceeds the supply. However, more than 90% the iron ores in China is of low grade with 30%Fe in average; the sub-marginal and ultra lean ores account for 40% of the total. 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.
