Which of the following minerals’ primary constituent is iron oxide containing equal amounts of iron (II) and iron (III) that is mainly used for steel manufacturing?
Answer & explanation
Correct answer: option 1
The correct answer is Option 1 - Magnetite
Out of the choices provided, the mineral whose primary constituent is iron oxide containing equal amounts of iron (II) and iron (III) and is mainly used for steel manufacturing is: Magnetite
Iron oxides are minerals that contain iron and oxygen. Magnetite is a specific type of iron oxide where the iron is present in both the +2 and +3 oxidation states (FeO•Fe2O3). This makes it the most magnetic of all the naturally occurring minerals.
