iron content of magnetite in zimbabwe

Magnetite is a rock mineral and one of the main iron ores with the chemical formula Fe 3 O 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 naturallyoccurring minerals on Earth Naturallymagnetized pieces of magnetite called lodestone will attract small pieces ...
