The properties of the raw hematite ore, reduced products, and magnetic concentrate were analyzed and characterized by a chemical analysis method, X-ray diffraction, optical microscopy, and scanning electron microscopy.
Magnetite is one of the most economically important iron ores. Because it has such a high iron content, magnetic iron ore deposits are highly prized. The iron from magnetite and hematite deposits is the source ore used to create steel used in modern infrastructure (3).
The chemical formula is Fe 3 O 4, commonly called ferrous-ferric oxide, and is valuable as an iron ore. The occurrence of magnetite is widespread. Difference Between Magnetite and Hematite
Chemical and mineralogical compositions of manganese ores from Central Asia deposits are investigated. The ores consist of the following minerals: pyrolusite, manganite, psilomelane, hausmannite, magnetite, hydrogoethite, calcite, quartz. Sample ore is regarded to be rich and

Properties. Magnetite is the most magnetic of all the naturally occurring minerals on Earth.  Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of iron, and this was how ancient people first noticed the property of magnetism.Lodestones were used as an early form of magnetic compass.
Magnetite is an iron oxide with the chemical formula Fe 3 O 4 whereas hematite is an iron oxide with the chemical formula Fe 2 O 3. Magnetite iron is in +2 and +3 oxidation states whereas, in hematite, it is only in +3 oxidation state.
The formation pathways, mineral properties, and applications of magnetite and green rust are currently active areas of research in geochemistry, environmental mineralogy, geomicrobiology, material sciences, environmental engineering, and environmental remediation.

Trivia. Magnetite was renamed to Iron Ore but was then changed back to Magnetite shortly afterward.. In real life, Magnetite is often mined and used as a source of iron as an Iron Oxide Crystal.
Magnetite is the primary oxide of iron found in meteorites (and thus presumably in asteroids). Thermite is a mixture of powdered magnetite and powdered aluminum. When ignited, the aluminum fuel burns using the magnetite as an oxidizer, resulting in much heat, aluminum oxide (corundum), and molten iron.
Magnetite grains in lateritic saprolite have altered in situ to porous hematite (martite) grains. Hematite occurs as relatively large (∼ 1 μm) platy crystals, triangular arrays of small (0.01–0.05 μm) lathlike crystals and very small (< 100 Å) platy anhedral particles.
