Magnetic separation of hematitecoated Fe3O4 particles ...
2011415 The products of conventional and surfactantassisted ballmilling of magnetite powder were tested as potential arsenic adsorbents able to be recovered by means of a lowfield magnetic separation process. Large hematitecoated 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)

2015218 When subjected to magnetic separation, the coated ore produces an iron concentrate containing 60.2% Fe with an enhanced recovery of 56%. The AFM studies indicate that the coagulation of hematite particles with the oleate colloidal magnetite facilitates the higher recovery of iron particles from the low grade BHJ iron ore under appropriate conditions.

2002121 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.
