University of Minnesota’s Mineral Pages: Calcite

The importance of iron ore to human society should be obvious, but magnetite has also played a subtler, but equally important, historic role in human civilization. Early on, people discovered that striking magnetite ‘lodestone’ against pieces of iron would magnetize the iron. This magnetized iron was used to make the first compasses, which greatly expanding our ability to navigate the ...

Difference Between Magnetite and Hematite Definition ...

31/01/2018  What is Magnetite. Magnetite is an iron ore where iron can be found in the form of Fe 3 O 4. Magnetite is ferromagnetic, which means, magnetite particles are attracted to an external magnetic field; magnetite particles can act like tiny magnets when magnetized. Magnetite is ferromagnetic since it has both Fe 2+ and Fe 3+ ions that have many unpaired electrons. The presence of unpaired ...
