Alternative route for magnetite processing for lower carbon
ABSTRACT Magnetite is relatively harder to reduce compared to hematite and present practise of magnetite processing involves its oxidation to hematite during pelletisation, followed by subsequent reduction in the blast furnace In this paper, we establish the feasibility of forming a reducible CaFe3O5 (CWF) phase through the addition of lime to Vanadium is the byproduct of commercial processes such as lead and zinc production in Namibia, from iron ore deposits in Finland and Norway, and from bauxite residues in France ( Vanadium, 2003 ) The two iron ore mines in Finland and the Rødsand mine in Norway were closed during the 1980s ( Bauer et al, 2002 )Processing of vanadium: a review ScienceDirect

Iron phosphate mediated magnetite synthesis: a bioinspired
Since magnetite is a mixed valence iron oxide (Fe 2+ Fe 2 3+ O 4), Fe 2+ ions were added to the system at this point with a stoichiometric ratio for Fe 3+: Fe 2+: H 3 PO 4 of 2: 1: 3, resulting in a mixed valence iron phosphate precursor phase Initially, this precursor phase was attained in a stepwise reaction Fe 2+ ions were added to the isolated and washed Magnetite (Fe3O4) nanoparticles (NPs) are attractive nanomaterials in the field of material science, chemistry, and physics because of their valuable properties, such as soft ferromagnetism, halfmetallicity, and biocompatibility Various structures of Fe3O4 NPs with different sizes, geometries, and nanoarchitectures have been Applied Sciences Free FullText Fe3O4 Nanoparticles: Structures
