Since iron ore minerals are formed similarly, the two types may have combined during their chemical formation process. When this occurs, the chemical composition of hematite changes, making the hematite weakly attracted to magnets. As a result, it's possible to mistake a hematite specimen for either pyrrhotite or magnetite.
