Magnetite is attracted to magnets and can be magnetized to become a permanent magnet itself. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces of iron, which is how ancient peoples first discovered the property of magnetism. Today it is mined as iron ore.

distribution of iron ore resources in the world - Mobile . Production and Distribution of Iron Ore around the . 2020-1-28 China now emerged as a leading iron ore-producing country in the world. Till 1975, its production of iron ore in the world was only 6.5 per cent, but in year 2000, China produced 24.3 per cent iron ore of the world.
Magnetite, a naturally magnetized mineral, has been known since antiquity. The needle of a magnetic compass was made from it more than 2,000 years ago in China. But magnetite is a weak magnet the magnetic properties of iron are much stronger.

Magnetism was first discovered in the ancient world, when people noticed that lodestones, naturally magnetized pieces of the mineral magnetite, could attract iron. The word magnet comes from the Greek term magntis lithos, the Magnesian stone, lodestone. In ancient Greece, Aristotle attributed the first of what could be called a scientific discussion of ...
Naturally magnetized magnetite is also called lodestone. A reaction between magnetite and oxygen can form hematite. Small amounts of magnetite can be found in most igneous and. Magnetite is a block of natural raw material found in the Fossil layer not far below the surface, in caves or mineshafts that you dig yourself, together with Limestone ...
This type of device is called a low-gradient magnetic separator and is effective when applied to larger, more strongly magnetic particles such as the concentration of iron or If the applied magnetic flux density is increased beyond 2 tesla, the device becomes useful down to very fine particles with extremely weak paramagnetic susceptibiliti.

The Magnetic Minerals are few, but the property is important because of this fact. Once a specimen is established as magnetic, identification becomes a rather routine exercise. The mineral magnetite is named after this characteristic.. Magnetism occurs most often when there is an imbalance in the structural arrangement of the iron ions.
A magnet forms when the magnetic dipoles in a material orient in the same general direction. Iron and manganese are two elements that can be made into magnets by aligning the magnetic dipoles in the metal, otherwise these metals are not inherently magnetic.Other types of magnets exist, such as neodymium iron boron NdFeB, samarium cobalt SmCo, ceramic ferrite magnets, and aluminum
Any material that has these two conditions is called ferromagnetic. Iron is the most common ferromagnetic element. Two other ferromagnetic elements are nickel and cobalt. However, several other substances can be ferromagnetic when they are heated or combined with other materials.
Magnetite is an important ore of iron. Well formed crystals are popular among mineral collectors, and the magnetic Lodestone variety is frequently sold in hobby shops to amateur collectors. Magnetite is also of significant interest to the science community due to its strong magnetic properties.
