  • Oxidation of magnetite concentrate powders during

    2005-1-6 · Oxidation of magnetite pellet concentrates (from LKAB, Sweden) during drying and storage was studied using thermogravimetric analysis (TGA). The Fe 2+ content of a standard LKAB pellet feed decreased by 0.2% during heat treatment at 105 °C for 2 days. The results indicate that magnetite concentrates of pelletizing fineness already start to oxidize to γ-hematite during drying at 105 °CInfluence of the olivine additive fineness on the,2003-6-1 · Oxidation of magnetite to hematite is a reversible reaction. If the hematite phase is clean, the hematite starts to dissociate back to magnetite at 1457 °C (in air). If the pellet contains components that form a solid solution with the hematite phase, the dissociation starts several hundred degrees earlier.
