SHP 30 Carboxyl Iron Oxide Nanoparticles Maximizing the recovery of fine iron ore using magnetic

The commercial magnetic separator is for the separation of magnetic beads larger than 100 nm Their magnetic gradient is not enough to separate our iron oxide nanocrystals smaller than 100 nm Q How do I purify the iron oxide nanocrystals to remove the reaction regents and are magnetic haematite being paramagnetic and magnetite being ferromagnetic This therefore means that magnetic separation can be applied in principle to all fine iron ore beneficiation plants While flotation has a considerable capacity advantage over magnetic separation the real advantage of magnetic separation over flotation in fine iron
