Commonly Used Processing Processes of Hematite - Xinhai

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. Generally, in order to ...

SUMMARY. The characterization of magnetic minerals in rocks often uses methods that measure induced magnetization. When rocks, sediments or soils contain two magnetic phases, in which one has a high saturation magnetization (M S), for example magnetite, and the other a low M S, for example hematite, the induced magnetization will be dominated by the stronger phase.
