Study the hematite reduction kinetics by the magnetic
2020-12-1 A continuous magnetization measurement method was used to obtain the temperature programmed reduction (TPR) profile. The influence of the external magnetic field on the dynamics of the process is investigated. It was shown that the TPR profile depends both on the magnitude of the applied field and on the particle size of hematite.

Commonly Used Processing Processes of Hematite
2021-2-12 Roasting-magnetic separation of hematite is generally applicable to hematite with fine grain size, low content of useful elements and low content of harmful elements. The hematite processing process requires the ore to be magnetized and roasted to convert the hematite or martite into magnetite, and then separate them by the magnetic separator with a weak magnetic field.
