Fine magnetite mixed into a water suspension is commonly used in coal preparation to create a pseudo- specific gravity great enough to effect separations between coal and associ- ated impurities. The magnetite must not only be reclaimed but must also be cleaned to prevent coal and impurities from building up in the washing cir- cuit.

Magnetic flow meters, also known as electromagnetic flow meters or mag meters, are often selected because they are obstruction less, cost-effective, bi-directional, and provide highly accurate volumetric flow measurement. A range of liner materials, electrode options and line sizes accommodate a wide variety of process applications.

This process, since it functions by way of the brushing motion of the small magnetic pins against the parts, also shines and polishes the parts. There is no residue left behind so there is no need for an extra step in the process to clean the batch of parts.

Brief History. Manganese has been used since ancient times although the etymology of its name is complex. In ancient times, the term "magnes" referred to two black minerals mined in Magnesia, now in modern-day Greece, said minerals of which were believed to have two distinct genders.

One common type of gold deposit is one where the gold is associated with the mineral magnetite where the gold is formed in skarns of granular magnetite. The mineral has a chemical formula Fe 3 O 4 that is often found in contact metamorphosed areas associated with intrusions of magma into carbonate or silico-carbonate rocks the intrusion itself is usually granite or monzonite-syenite.

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 ...

Annealing has been a widely used technique in metallurgy for quite some time. However, a relatively new technique, called magnetic thermal annealing, puts a new spin on this age-old method. The major difference between the two heat treatments is that in magnetic annealing, an external magnetic field is applied during the annealing process.
