Magnetic separation of hematite

Magnetic separation of hematitecoated Fe3O4 particles The slightly lower separation degree could be explained by the broad size distribution and the reduction of magnetic interactions due to the thick hematite coating in Fe 3 O 4 /αFe 2 O 3 particles Unlike the 30 nm Fe 3 O 4 particles which preserve their magnetic properties at different acidities the recovery of Fe 3 O 4 /αFe 2 O 3...
