Magnetite and hematite can be separated from each other using their magnetic properties. Magnetite is ferromagnetic and hematite is paramagnetic. Therefore, these substances can be separated using low-intensity magnetic separation method. Here, an induced roll magnetic separator with a magnetic field with a 0.04 Tesla intensity is …

Upgrading of the LR Rutile was possible by using magnetic separation. With a low intensity magnetic separator (field intensity below 0.67 T), reduction roasting of the sample improved the separation. However, when a high intensity magnetic separator was used, the separation could be achieved without the need for reduction roasting.
