Magnetite is a member of the spinel group which has the standard formula A(B) 2 O 4. The A and B represent usually different metal ions that occupy specific sites in the crystal structure. In the case of magnetite, Fe 3 O 4, the A metal is Fe +2 and the B metal is Fe +3; two different metal ions in two specific sites. This arrangement causes a ...

What is magnetite ore? Mishainik / Adobe Stock. The mineral magnetite is a highly magnetic mineral found in solid and crystal forms. Magnetite actually has higher iron content than hematite. However, while hematite ore generally contains large concentrations of hematite, magnetite ore tends to hold low concentrations of the mineral magnetite.

What are the different types of iron oxide? The different types of iron oxide are magnetite, maghemite and hematite. The colour of magnetite is black. Hence it is also referred to as black iron oxide. The colour of maghemite is yellow. Hence it is also referred to as yellow iron oxide. The colour of hematite is red.
