    Magnetite & Lodestone Mineral Photos, Uses, Properties

    Magnetite is very easy to identify. It is one of just a few minerals that are attracted to a common magnet. It is a black, opaque, submetallic to metallic mineral with a Mohs hardness between 5 and 6.5. It is often found in the form of isometric crystals. It is the most strongly magnetic mineral ...

    Magnetite resembles a number of other metal ores, but it is the only common mineral that exhibits magnetism. So magnetism alone is sufficient to distinguish relatively pure magnetite samples. It is more difficult to distinguish cases where magnetite is mixed with

    Q & A: Is gold magnetic? Department of Physics ...

    Oct 22, 2007· Shawn Pure gold is not magnetic. That is, it doesnt form a magnet on its own. If you put it in a magnetic field it will magnetize a tiny bit, but only so long as its in the field. and the direction of the magnetizaqtion makes it weakly repel the magnet. There are alloys of gold, for example gold with more than about 20% of the atoms replaced by iron, which do magnetize on their own, at ...

    Magnetite

    Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces ...

    Magnetic separation

    Recycling centres use magnetic separation often to separate components from recycling, isolate metals, and purify ores. Overhead magnets, magnetic pulleys, and the magnetic drums were the methods used in the recycling industry. Magnetic separation is also useful in mining iron as it is attracted to a magnet.
