Chromite: The only mineral ore of chromium metal

Magnesium frequently substitutes for iron in chromite. A solid solution series exists between the mineral chromite (FeCr 2 O 4) and the isomorphous mineral magnesiochromite (MgCr 2 O 4).Intermediate specimens can be rich in iron ((Fe,Mg)Cr 2 O 4) or magnesium ((Mg,Fe)Cr 2 O 4).For convenience in communication, these minerals are often referred to collectively as "chromite."

Iron ore pellets are spheres of typically 8–18 mm (0.31–0.71 in) to be used as raw material for blast furnaces. They typically contain 67%-72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolostone and olivine is added and Bentonite is used as binder.

What are minerals used for? | Anglo American

Mined minerals are an important part of human nutrition. Iron, manganese, selenium, and calcium all provide day-to-day nutrients that the body needs in order to function.
