Filter Capacity Predictions for the Capture of Magnetic ...

Abstract: We present experimental and theoretical methods to predict maximum and working filter capacities for the capture of superparamagnetic microparticles through high-gradient magnetic separation (HGMS). For this, we employed various combinations of nine different HGMS filter matrices and two types of superparamagnetic microparticles. By calculating the separated particle mass per …

Chromatography | chemistry | Britannica.com

The driving force for solute migration is the moving fluid, and the resistive force is the solute affinity for the stationary phase; the combination of these forces, as manipulated by the analyst, produces the separation. Chromatography is one of several separation techniques defined as differential migration from a narrow initial zone.

What are Magnetic Separators? (with picture) - wisegeek.com

Magnetic separators are also used to remove materials which could damage or foul equipment, in a pre-processing step. Separators can also be used to sort various types of metal, with a series of separators varying in intensity to pull out strongly and weakly magnetic materials at different times.

Magnetite - Wikipedia

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 Method - Mineral Processing & Metallurgy

Magnetic separation is a process used to separate materials from those that are less or non­magnetic. All materials have a response when placed in a magnetic field, although with most, the effect is too slight to be detected. The few materials that are strongly affected (magnetised) by magnetic fields are known as "Ferromagnetics", those lesser (though noticeably) affected are known as ...
