Iron impurities may be removed from volumes of molten aluminum or magnesium metals or alloys by applying a static magnetic field gradient to each of the molten metal volumes, or melts. The magnetic field gradient is applied to each of the melts so that separate-phase iron impurities suspended therein will move in the direction of the applied magnetic field and become concentrated in a ...

Magnetite - Wikipedia

Magnetite is a 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 of ...

Isotope separation - Wikipedia

Isotope separation is the process of concentrating specific isotopes of a chemical element by removing other isotopes. The use of the nuclides produced is various. The largest variety is used in research (e.g. in chemistry where atoms of "marker" nuclide are used to figure out reaction mechanisms). By tonnage, separating natural uranium into enriched uranium and depleted uranium is the largest ...

Magnesium (Mg) and water - Lenntech

Magnesium metals are not affected by water at room temperature. Magnesium generally is a slow-reacting element, but reactivity increases with oxygen levels. Furthermore, magnesium reacts with water vapor to magnesium hydroxide and hydrogen gas: Mg (s) + 2H 2 O (g) -> Mg (OH) 2 (aq) + H 2 (g) Magnesium fires cannot be extinguished by water.
