  • Gravity separation - Wikipedia

    Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.

  • Gravity Separation - an overview ScienceDirect Topics

    Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2-stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm ...

  • Flotation ore dressing Britannica

    Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to

  • Gravity Separation

    Gravity Separation . Gravity separation uses differences in specific gravity (SG) between various minerals to achieve a separation, and is normally a wet process although examples of dry gravity separators exist. Gravity separation works best when there is a large difference in the SG in the minerals to be separated, and the particle size is similar and not excessively fine, and shape is ...

  • Magnetic Separation Method - Mineral Processing

    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 ...

    Gravity Concentration — the separation of minerals by virtue of specific gravity — is one of the oldest forms of mineral processing. Whilst its relative importance has declined in the twentieth century, the high cost of alternative processes, along with the development of a range of high capacity devices has led to something of a renaissance of gravity concentration.
