Rank.Is Hematite Magnetic? - Techiescientist,15/06/2021· Hematite is one example which changes its magnetic behavior with a change in the temperature. At lower temperatures, hematite acts as an antiferromagnet and at higher temperatures, it becomes a paramagnet. In case, when there is no external applied magnetic field, hematite does not respond to a magnet whatsoever. But in the presence of an applied external magnetic field, hematiteEFFECT OF MAGNETITE, HEMATITE AND PELLET SCREENINGS,LKAB magnetite and hematite fines are to be classified as coarse concentrates, an increase of these materials can contribute to a finer particle size distribution between one to three millimetres.
