Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.
j Separation Techniques. Magnetic mineral separation techniques are invariably selective, and not fully representative of the grain size and composition of magnetic minerals present in the sample; however, magnetic separation may be necessary for SEM/TEM, X-ray, Mossbauer, or chemical analyses.

High intensity wet magnetic separators. Developing 7000 20 ,000 gauss. The need for a wet magnetic separator capable of economically separating the less magnetic minerals such as hematites and ilmenites can be seen from the volume of production of such minerals.
Magnetic separators exploit the difference in magnetic properties between the minerals in a deposit and are used to concentrate a valuable mineral that is magnetic (e.g., magnetite from quartz), to remove magnetic contaminants, or to separate mixtures of magnetic and nonmagnetic valuable minerals. An example of the latter is the tin-bearing
A magnetic separator filters/traps to remove the metal particle, And not just in food: even the smallest foreign bodies are undesirable in pharmaceutical, chemical or mineral bulk streams and lower the quality of the finished product. 2. Magnets prevent damage to your production machinery.
Mineral size. Dry magnetic separation function for bulk, coarse particle separation, but also fine mineral separation, while wet magnetic separator can not sort large bulk minerals, most are effective for fine or even fine particles, except for a few models that can select coarse particle.
Consequently, the magnetic force does not decline in the manner of an IMR set with a large air gap. Magnetic Separators Application in Mineral Industry One of the oldest tools used in mineral concentrating is the magnetic separator. Virtually every mineral handling system has need for some type of magnetic equipment in two types of basic usage.

Gravity separation relies on differences in material mass to separate minerals. Methods include jigs, sluices, spirals, shaking tables, fine particle separators, and hydrosizers and cyclones. Gravity separation is separation based on weight only and is directly affected by particle size since volume is proportional to weight.
The final high value mineral products report as Zircon, Rutile and Ilmenite. The recovery of non-magnetic material is largely dependent upon a number of factors, including but not limited to dew point, ambient temperature, feed rate, mineral size distribution, specific gravity and mineral content in head feed.
Magnetic Separation is the process of separating components of mixtures by using magnets to attract magnetic materials.
