Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe3O4. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet The relationships between magnetite and other iron-rich oxide minerals such as . These are used in several ways, in addition to being fun to play with.

Why is iron so prominent in this planet and others? Magnetite gets its name because it has the rare property of being magnetic. .. 2, Look at what you encounter in a bottle of mineral water besides water and hydrogen carbonate: Sodium,
Jan 25, 2018 soil from your backyard; neodymium magnet; a piece of paper Please keep them away from children who still put everything into their mouths. Find soil from other sources e.g. school playground and see if they produce a different amount. The mined iron ore is then processed to give molten iron.
separation from non-magnetic gangue minerals was facilitated. Keywords: Hematite; Fluidized advantages over the other roasting techniques: ease of control due to Besides, the roasting temperature for conventional fluidized bed furnace
The principal iron ores are hematite Fe2O3 and magnetite Fe3O4. Magnetite is an iron oxide mineral which is generally black in colour and highly magnetic, the latter .
