Iron ore beneficiation need of general industrial indicators
| Ore type | ω(TFe)% | |
| Boundary grade | Industrial grade | |
| Magnetite | ≥20 ω(mFe)≥15 | ≥25 ω(mFe)≥20 |
| Brown iron ore hematite iron ore Ling | ≥25 ≥20 ≥25 | 28～30 ≥25 ≥30 |
| Note: If the ore is easy to be collected, easy to select, economical, or contains associated components that can be comprehensively recovered, the total iron (TFe) content requirement can be appropriately reduced; the content of iron silicate, iron sulfide and iron carbonate in magnetite ore is higher. High, using the magnetic iron (mFe) standard. | ||
