Recovery enhancement of magnetite fines in magnetic separation ...

The magnitude of the fluid drag force exceeds the magnetic force exerted on such particles. Thus, fine magnetic particles are usually not picked up effectively by magnetic separators, resulting in the loss of valuable minerals. Magnetic separation applied to ultrafine magnetite particles after size enlargement by polymer...

Magnetic Separation - Mine Engineer

Particles that are attracted to the magnetic field are called magnetic. But, there are two classifications of magnetic particles, strongly magnetic particles, such as iron and magnetite, and weakly magnetic particles, such as rutile, ilmenite, and chromite. Strong magnetic particles may be easily separated with a separator having...

Maximizing the recovery of fine iron ore using magnetic separation

The main economic iron minerals are magnetic, haematite being paramagnetic and magnetite being ferromagnetic. This, therefore, means that magnetic separation can be applied, in principle, to all fine iron-ore beneficiation plants. While flotation has a considerable capacity advantage over magnetic separation, the real...

Magnetite - Wikipedia

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. Magnetite 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.

Magnetic Separation

Magnetic separation takes advantage of differences in the magnetic properties of minerals. Minerals fall into one of three magnetic properties: ferromagnetic, paramagnetic and diamagnetic. Ferromagnetic minerals are themselves magnetic (i.e., magnetite and pyrrhotite) and can be easily separated from other minerals with...

Does Using A Magnetic Separator Lose Fine Gold?

Because magnetite can attracts itself in a magnetic field, it might be possible for fine gold to get trapped between grains of magnetite. If a magnetic separator is used and the magnetite discarded, fine gold could be lost. Or could it? That's what this page will attempt to answer through the following experiment: Starting with a...
