  • Explaining magnetic separators

    What is Magnetic Separation? Magnetic Separation is one of the most common and important physical separation techniques.  The basic concept of a Magnetic Separator is that magnetically susceptible particles or bodies are separated from non-magnetic particles.  However, the simplicity stops there.  To enable different levels of separation from a wide range materials, there ...

  • Polyaniline/reduced graphene oxide/Fe3O4 nano-composite for aqueous Hg(II) removal

    To ease the adsorbent recovery and to increase the adsorption capacity of polyaniline (PANI), aniline was polymerized in the presence of a solvothermally prepared nano-composite of reduced graphene oxide and Fe3O4 (RGO/Fe3O4). The polyaniline was formed along the RGO/Fe3O4 composite in transmission electron microscope (TEM). The thus formed ...

  • Magnets: A viable alternative to flotation for sand producers

    Introduction The basic rudiments of mineral beneficiation have not changed for many years. The techniques have been improved, but are still essentially the same, using either a materials weight, density, shape or magnetic susceptibility to enable separation. For removing impurities from non-metallic minerals, such as silica sand, typical methods include Flotation, Gravity and Magnetic ...

  • The true value of magnetic separators and metal detectors in bulk handling

    Introduction The purpose of a bulk material handling may be to transport material from one of several locations to an ultimate destination or to process material such as ore in concentrating and smelting or handling materials for manufacturing. The handling of dry materials in loose bulk form involved the extensive use of static machinery such as belt conveyors, screw conveyors, and various ...

  • Magnetic seeding of non-magnetic adsorbent powders by coagulation using ferric chloride and magnetite

    A magnetic modification of conventional adsorbent powders to remove them rapidly from water is investigated. In this paper we study the possibility of using a non-magnetic adsorbent powder mixed with magnetite and a coagulant such as ferric chloride added after the adsorption to create magnetic flocs that can be magnetically separated (magnetic seeding). A natural zeolite and Na-activated ...

  • Facts About Ferrite Magnets

    Ferrite magnets are also referred to as ceramic or hard ferrite magnets. In the 1960s these magnets were developed to subsidize costly metallic magnets. Generally, they possess less energy compared to other magnets made of permanent materials. They are hard and relatively brittle. Since their creation, they have gradually won wide acceptance. This has been contributed by their excellent ...

  • Design low losses 6/8 switched reluctance motor

    The magnetic circuit of the conventional 6/8 switched reluctance motor (SRM) is re-designed to minimise the losses. The flux loops are shortened by making each two stator teeth incorporated in one magnetic circuit only. Subsequently, the flux does not flow in all parts of the stator yoke. The unused iron sections do not produce iron losses. Now, the stator consists of three separated sections ...

  • Preparation of magnetic alginate–layered double hydroxide composite adsorbents and removal of Cr(VI) from aqueous solution

    The aim of this study was to investigate the removal of Cr(VI) from aqueous solution using magnetic alginate–layered double hydroxide (LDH) composites. Magnetic iron oxide and calcined Mg-Al LDH powders were synthesized in the laboratory. The magnetic composites were prepared through immobilization of synthetic magnetic iron oxide and calcined Mg-Al LDH powders into an alginate matrix. ...

  • Synthesis of kaolinite/iron oxide magnetic composites and their use in the removal of Cd(II) from aqueous solutions

    Kaolinite/iron oxide magnetic composites (kaolinite/MCs) were used as adsorbent for the removal of Cd(II) from aqueous solutions. The influences of pH, ionic strength, solid/liquid ratio and temperature on Cd(II) sorption on kaolinite/MCs were evaluated. The results showed that the removal of Cd(II) on kaolinite/MCs was strongly dependent on pH and ionic strength. An optimal kaolinite/MCs ...
