Which ore can separated using magnetic separator

  • which ore can be separated by magnetic separation

    The ore which can be attracted by the magnetic field can be concentrated by the process of magnetic separation. Among the ores mentioned in table 6.1, the ores of iron such as haematite (Fe 2 O 3 ), magnetite (Fe 3 O 4 ), siderite (FeCO 3 ), and iron pyrites (FeS 2) can be separated by the process of magnetic separation


    ADVANCES IN MAGNETIC SEPARATION OF ORES Magnetic separation of iron ores is one of the fastest-growing segments of the minerah beneficiation industry. The tonnage of taconite ores processed annually by magnetic separation toill, in a few years, reach 100 million. by L. A. ROE M agnetic separation occupies an attractive posi

  • Developments in the physical separation of iron ore

    Jan 01, 2015 Of the oxidized iron ores, specularite is most susceptible to magnetic fields, as it is better crystallized, followed by martite and hematite. It is therefore easier to upgrade specularite using magnetic separation, compared with martite and hematite

  • Magnetic Separation and Iron Ore Beneficiation

    Oct 04, 2018 Magnetic separator separates the iron ore feed material into two or more components. If the purpose is to produce a magnetic concentrated iron ore then the other component which is non-magnetic is the tailings. In some cases there can also be a possibility of separating the less magnetic third component which is called middlings

  • Magnetic Ore Separator

    Jan 16, 2017 In examining the results of separation, we find that the heads compose one-half of the original material by weight, and carry 67 per cent, of iron, or 92.5 of magnetic oxide, equal to 46.3 out of the original 48.3 in the crude ore, while the tails contain the remainder, which is 2 per cent, of magnetic oxide out of the original 48.3 in the crude material; but this 2 per cent, is 4

  • Magnetic Separator - an overview | ScienceDirect

    As magnetic separators progress toward larger capacity, higher efficiency, and lower operating costs, some subeconomic iron ores have been utilized in recent years. For example, magnetite iron ore containing only about 4% Fe (beach sands or ancient beach sands) to 15% Fe (iron ore formations) and oxidized iron ore of only about 10% Fe (previously mine waste) to 20% Fe

  • Magnetic Separators - SolidsWiki

    Minerals such as hematite, limonite, and garnet are weakly magnetic and can be separated from nonmagnetics by the use of high-intensity separators. Magnetic separation method is based on the difference of mineral magnetic, bearing different forces in the magnetic field of magnetic separator, resulting in material separation

  • The ore that can be concentrated by magnetic separation

    The ore that can be concentrated by magnetic separation method is pyrolusite (M n O 2 ). In this method, the ferromagnetic and non-magnetic particles in the ore are separated by an electromagnetic separator

  • Magnetic separation - Wikipedia

    Magnetic separation is the process of separating components of mixtures by using a magnet to attract magnetic materials. The process that is used for magnetic separation separates non-magnetic materials from those that are magnetic. This technique is useful for the select few minerals which are ferromagnetic (iron-, nickel-, and cobalt-containing minerals) and

  • Magnetic Separator - an overview | ScienceDirect Topics

    Magnetic complexes from larger volumes of suspensions (up to approximately 500–1000 mL) can be separated using flat magnetic separators. More sophisticated magnetic separators are available, e.g. those based on the quadrupole and hexapole magnetic configuration

  • Magnetic Separation - Department of Earth and Planetary

    The magnetic separator consists of a large electromagnet through which mineral mixtures can be passed on a metal trough which is divided near its exit end. Varying the strength of the magnetic field and/or slope of the separation trough is used to separate minerals. All forms of mineral separation suffer from one difficulty

    Aug 07, 2020 The new process can promote iron precipitate aggregation and growth on the surface of the magnetic iron ore seeds. A core-shell structure was formed of iron precipitate and magnetic iron ore seeds, which can be magnetized and coalesced in magnetic field, accelerating the solid-liquid separation. The efficient magnetic flocculation and

  • Heavy Minerals and Magnetic Separation - How We

    The simplest form of magnetic separation is by hand magnet, a procedure which works for only one common mineral - magnetite. Other minerals having magnetic susceptibility are separated by using an apparatus that can generate strong electromagnetic fields. The Frantz separator (Fig. 1) incorporates an electromagnet with two elongate pole pieces
