Hematite is an iron oxide with the chemical formula Fe2O3; magnetite is also an iron oxide but with the chemical formula Fe3O4. Another important difference between hematite and magnetite is that hematite appears in a variety of colors, but magnetite is only black in color.

 · Yes, hematite being an iron ore is magnetic in nature. It is antiferromagnetic in nature below the Morin transition ie; approximately at 250 K. And it acts as a weak ferromagnet above the Morin transition and Neel temperature, which is approximately 948 K. In addition to this, hematite above the Neel temperature is a pure paramagnet.

 · It was found that the feed particle size and the drum rotation speed have significant influences on the separation performance, and a magnetic concentrate assaying 36.22% Fe with 75.97% recovery is achievable from the ore assaying 29.14% Fe at a coarse particle size below 10 mm.

 · Hematite's magnetic properties are caused by unpaired electrons. It is paramagnetic due to the presence of only ferric ion (Fe +3). As a result, hematite can be separated from a mixture using high-intensity magnetic separation methods that employ magnetic fields ranging in intensity from 0.02-4.0 Tesla. Hematite is a metallic grey mineral.

What is Magnetic Hematite? Magnetic Hematite starts out as the natural or raw form of hematite. This raw form is made up of Iron Oxide that contains small amounts of titanium and can be found in black, gray to silver gray, brown to reddish brown or red. Gemstone quality hematite is an opaque stone that looks similar to metal.
