Magnetic separation of hematite-coated Fe3O4 particles ...

2011-4-15  The products of conventional and surfactant-assisted ball-milling of magnetite powder were tested as potential arsenic adsorbents able to be recovered by means of a low-field magnetic separation process. Large hematite-coated Fe 3 O 4 particles obtained without the addition of surfactant were found to be much more efficient to reduce arsenic levels below the international regulation limit (10 μg/L)

2002-12-1  The magnetic susceptibility of the hematite (Fe 2 O 3) sample used in this work, measured at 0.95×10 −6 m 3 /kg, is lower than that of the ilmenite sample (2.18×10 −6 m 3 /kg). Hematite contains ferric irons and cannot be oxidized further. In fact, oxidation roasting of hematite did not change its magnetic susceptibility.
