magnetic separation of minerals

  • Mineral processing - Wikipedia

    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.

  • Magnetic Separators For Mineral Process | Master Magnets

    Magnetic Separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material with those who are magnetic. This technique is useful for not all, but few minerals such as ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic (materials that are less ...

  • Magnetic Properties: Mineral Properties - The Mineral and ...

    Magnetic properties of minerals are defined as follows: Ferromagnetism describes strong attraction to magnetic fields. This property is exhibited in few minerals, notably Magnetite and Pyrrhotite. Paramagnetism is weak attraction to magnetic fields. The attraction is usually discernible, but it may be so weak that it is undetectable.

  • Magnetic Separation - an overview | ScienceDirect Topics

    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, Moss, or chemical analyses. The importance of fine SD grains as remanence carriers emphasizes the ...

  • Magnetic susceptibility of geologic materials

    Separation tends to overestimate the ferrimagnetic mineral content, while visual or microscopic examination tends to underestimate it. Soils (Summarized from Breiner, 1973) Magnetic susceptibility of soils might be expected to be related to the magnetite content of parent rocks. However, magnetite is more resistant to weathering than other ...

  • Magnetic susceptibilities of minerals - USGS

    Magnetic separation of minerals is a topic that is seldom reported in the literature for two reasons. First, separation data generally are byproducts of other projects; and second, this study requires a large amount of patience and is unusually tedious. Indeed, we suspect that most minerals probably are never investigated for this property.

    to the higher side of the chute. Magnetic separation takes place as the mineral grains move down the first one-quarter of chute length; then, about one-third of the way through the magnetic field, a divider in the chute keeps the magnetic and nonmagnetic fractions apart, and the two fractions are collected in separate aluminum cups at

  • Magnetic Separation - Mine Engineer.Com

    Magnetic separation is generally a low cost method of recovery, unless high intensity separators are required. The electro-magnetic high intensity separators that produce 20,000 gauss, tend to be expensive. However, the rare earth magnetic separators are relatively inexpensive and can produce magnetic fields around 6,000 gauss.

  • Magnetic Separation - Department of Earth and Planetary ...

    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 a magnet since they will ...
