Unlike magnetite concentrates, hematite concentrates, especially specularite and pyrite cinder, are harder, denser with smooth surfaces, and less hydrophilic. Therefore, they are usually much more difficult to pelletize and require higher bentonite dosages and firing temperatures to achieve the minimum green and fired pellet quality.

Difference Between Magnetite and Hematite

31-01-2018  Magnetite and hematite are two forms of iron ores from which iron can be extracted. Magnetite contains iron in the form of Fe 3 O 4. Hematite contains iron in the form of Fe 2 O 3. The main difference between magnetite and hematite is that magnetite is ferromagnetic whereas hematite is paramagnetic. Key Areas Covered. 1. What is Magnetite

01-01-2019  In material sciences, hematite and magnetite are among the most important corrosion products of steel at elevated temperature (e.g., Bertrand et al., 2010, Yu et al., 2015). The transformation of magnetite to hematite can be expressed in term of a redox reaction, e.g., 2Fe3O4(mt) + 0.5 O2(g) ↔3Fe2O3(hm) (I) with: log f O 2 (g) = −2 logK (P,T)

Maghemite - an overview ScienceDirect Topics

Maghemitization is an iron-leaching process, usually occurring in the presence of water, that leaves the spinel lattice intact but one-sixth of the octahedral sites vacant. M s of maghemite is therefore somewhat lower than that of magnetite although T C is higher, intermediate between those of magnetite and rhombohedral hematite (αFe 2 O 3).
