Earth and Environmental Sciences

Although hematite is more abundant than magnetite, magnetite has the higher iron content, so magnetite iron ore deposits are highly sought after Economic magnetite deposits primarily occur in layered igneous rocks that formed from the slow cooling of magma, heavy mineral sedimentary deposits, and Early Proterozoic (25 to 16 billion years ago) marine precipitat.

Ilmenite

However hematite has a distinctly different streak Magnetite is also similar and easily confused with ilmenite, but ilmenite has a different crystal form and is not as strongly magnetic It is often associated with magnetite and therefore ilmenite is a minor ore of.

Titanium occurrence and distribution in the magnetite

Ilmenite and finally anatase increase in abundance as grade decreases, and also as the magnetite-hematite ratio increases at the boundaries between hematite and magnetite ore Textures suggest that uniformly distributed titania in the host-rock was preferentially taken up by hematite, and that greatest subsequent exsolution took place in those rocks with least hematite.
