Difference Between Magnetite and Hematite ...

Jan 28, 2012· Magnetite and hematite are important oxides of iron. Though there are several differences between them, the key difference between magnetite and hematite is that the iron in magnetite is in +2 and +3 oxidation states whereas, in hematite, it is only in +3 oxidation state. Magnetite is black in colour, but hematite has

Pyrrhotite - Wikipedia

Pyrrhotite is an iron sulfide mineral with the formula Fe (1-x) S (x = 0 to 0.2). It is a nonstoichiometric variant of FeS, the mineral known as troilite.Pyrrhotite is also called magnetic pyrite, because the color is similar to pyrite and it is weakly magnetic.The magnetism decreases as the iron content increases, and troilite is non-magnetic.
