  • Quinone-mediated dissimilatory iron reduction of hematite

    In the AQDS-free treatments, no obvious defects were observed on raw hematite {0 0 1} and {1 0 0} surfaces before the bioreduction process (Fig. 3a, 3b).Evident defects appeared on the surface of hematite {0 0 1} and {1 0 0} after 120 h of reduction, which can be mainly attributed to the changes in the ideal structure of Fe oxides caused by electrons injected into hematite .

  • hematite | Definition, Uses, & Facts | Britannica

    Hematite, also spelled haematite, heavy and relatively hard oxide mineral, ferric oxide (Fe 2 O 3), that constitutes the most important iron ore because of its high iron content (70 percent) and its abundance. Its name is derived from the Greek word for "blood," in allusion to its red colour. Many of the various forms of hematite have separate names. The steel-gray crystals and coarse

  • Hematite - Wikipedia

    Hematite, also spelled as haematite, is a common iron oxide with a formula of Fe 2 O 3 and is widespread in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3.It has the same crystal structure as corundum (Al 2 O 3) and ilmenite (FeTiO 3), with which it forms a complete solid solution at temperatures above 950 °C

    Nov 26, 2020· The hematite presented an IEP around pH 5.3, and below the IEP the hematite presented a positively charged surface, achieving 10 mV at pH 3. Above the IEP a negatively charged surface was observed, achieving −27 mV at pH 11. Thus, this flexibility of hematite makes it possible to interact with anionic and cationic surfactants.
