Synopsis The beneficiation of fine iron ore will increase in importance in the future because most new iron ore resources will be in the form of lower grade ore deposits that will require liberation of iron ore minerals at finer sizes. Generally this fine iron ore will be benefi-ciated to produce a pelletizing concentrate with very strict chemical and physical specifications. In addition

Beneficiation of low-grade fine-grained hematite ores becomes increasingly important due to rapid depletion of high quality iron ore resources. However, fine particles, especially ultra-fine particles, make efficient beneficiation of these ores more difficult. Therefore, methods to reduce the influence of fine particles must be considered to achieve better beneficiation performance. …

202516· A pre-enrichment, hydrogen-based mineral phase transformation (HMPT), and magnetic separation process was developed for ultra-low-grade iron ore. The pre-enrichment effectively removed one-third of the tailings, increasing the iron grade from 21.78% to 31.17%. This enrichment not only improved the quality of the raw material but also reduced the …

Most iron ore operations that require beneficiation of ROM ore to produce lump, fine (sinter), and pelletizing concentrate iron ore products will discard a slimes fraction to final tailings. This fraction can vary in particle size from –200 μm down to –10 μm. The general view is that this fraction is low grade in terms of iron ore mineral content and contains a significant concentration
