Magnetite
This mineral is magnetite.
The natural occurring magnets can be found in a natural state in the form of a magnetic ore,
Magnetic separation is technique used in metallurgyfor the concentration of ore particles. The principle of this method is that the magnetic ore particles can be separated from non magnetic impurities (gangue) or viceversa.
No, scheelite is not magnetic. It is a non-magnetic mineral that is commonly found as a tungsten ore.
No, but some types of iron-ore have a permanent magnetic field.
magnetic
Ferrous ore contains iron, which is magnetic. When you hold a compass near ferrous ore, the iron in the ore can affect the magnetic needle of the compass, causing it to deviate from its usual direction. By observing any unusual behavior in the compass needle, you can potentially detect the presence of ferrous ore nearby.
Yes, magnetic iron ore, such as magnetite, was used as a primitive compass because it has magnetic properties that align with the Earth's magnetic field. When suspended or placed on a floating object, the iron ore would align itself in the north-south direction, indicating the cardinal directions. This provided early navigators with a basic way to orient themselves.
Iron ore tends to align itself in a North-South position due to the Earth's magnetic field. The magnetic minerals in iron ore are influenced by the Earth's magnetic field, causing them to align themselves in a North-South direction as the ore solidifies. This alignment can be observed in rocks that were formed during periods when the Earth's magnetic field was in a specific orientation.

The mineral found in Siberia are coal, iron ore, manganese, copper ore, and zinc in Asia.
