  • Removal of Pb(II) and Cu(II) from aqueous solution using multiwalled carbon nanotubes/iron oxide magnetic composites

    Multiwalled carbon nanotubes (MWCNTs)/iron oxide magnetic composites (named as MCs) were prepared by co-precipitation method, and were characterised by scanning electron microscope (SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) in detail. The prepared MCs were employed as an adsorbent for the removal of Pb(II) and Cu(II) ions from wastewater in heavy metal ion pollution ...

  • A feasibility study of magnetic separation of magnetic nanoparticle for forward osmosis

    It was recently reported that a UK company has developed a naturally non-toxic magnetoferritin to act as a draw solute for drawing water in forward osmosis process. The gist of this technology is the utilization of the magnetic nanoparticle and high-gradient magnetic separation for draw solute separation and reuse. However, any demonstration on this technology has not been reported yet. In this ...

  • A Masterful Performance In Ferrous Recovery

    Earlier this year, Master Magnets were contacted by Guernsey Recycling Ltd about an under-performing Drum Magnet that was supplied by one of Mastermag’s competitors. They were keen to find out whether or not Master Magnets felt that carrying out a refurbishment on their existing drum would enhance its performance. So that Master Magnets could get a better idea of the drums current condition ...

  • The trajectories of charged particles moving at relativistic speeds inside particle separators – a fully symbolic solution

    Predicting the motion of charged particles through electromagnetic fields is a very important feature in the design of particle accelerators since it provides the very important function of separating the particles according to their charge, mass and velocity (Gold and Nusinovich, 1997; Chu, 2004). In our paper we consider the general case when the electric field E and magnetic field B have an ...

  • Master Magnets introduce the `R` type

    Eddy Current Separators are one of the most widely used types of magnetic separation equipment in the world today and are being increasingly used in various industrial applications for the separation of non-ferrous metals, such as aluminium and copper, from various types of product. Applications that often call for Eddy Current Separators include the separation of aluminium from crushed glass, ...

  • One hundred years of superconductivity: science, technology, products, profits and industry structure

    Superconductivity was empirically discovered 100 years ago. While scientific efforts were rewarded by no fewer than seven Nobel Prizes, there has been only one major application: MRI. The unfulfilled potential of other electrical and electronic applications resulted in the acquisition of the MRI division of Oxford Instruments by Siemens in 2002 and of IGC by Philips in 2006. In this paper, we ...

Sinarmentari Indoprima the Indonesia distributor for OEI installed an OEI magnetic filter rod (3RNC5812) in an existing T-Strainer on the finished product line (photo A).RESULTS: Photo B: contamination captured 44 grams ...


  • Contractor’s grinder upgrade opens doors for new opportunities

    For Jim Soukup, president of Soukup Construction, Inc., upgrading his grinder fell into the category of a “no-brainer.” A combination of less-than-ideal performance and growing maintenance costs made their existing grinder inefficient, if not altogether ineffective. Making the move to a bigger, more productive unit, a Morbark Model 4600 Wood Hog horizontal grinder, has not only vastly improved ...


  • Application of magnetic separation technology for the recovery of colemanite from plant tailings

    In this study, colemanite was recovered from tailings produced by the Kestelek (Turkey) Processing Plant by magnetic separation. Magnetic susceptibility measurements revealed that colemanite is diamagnetic in character whereas gangue minerals are weakly paramagnetic, apparently due to the presence of the iron-bearing silicates such as smectite and, to a less extent, illite. Three-stage magnetic ...

  • Magnetic nanocarriers: from material design to magnetic manipulation

    Magnetic nanocarriers play an increasing role in various biomedical applications such as the separation of magnetically 'tagged' DNA, drug delivery or identification of biological species. Recent developments in nanotechnology allow the fabrication of both artificial nanocarriers and magnetic separation devices which may achieve great performances at an incredibly small-volume sample handling. ...

  • Development of joining procedure for pole pieces of the electromagnet of the diverse safety rod in a fast breeder reactor

    In the prototype fast breeder reactor, the electromagnet for the diverse safety rod is welded using a non-magnetic filler to separate the magnetic poles. The pole pieces are made of soft iron, and the non-magnetic nickel base ERNiCr-3 was chosen as non-magnetic filler wire. The procedure followed for joining the pole pieces consisted of weld build-up of the inner and outer core pieces with ...

  • The Electro-magnetic forces

    In this research we will introduce the new technique Electro– magnetic forces to filtrate the lubricant oil from the dust of the natural or artificial solid metals. DC type voltage within the range of 0–30 Volts were used on a steel meshes (Porosity=0.83) and for the steel discs (P=0.0885), while the range of 0–200 Volts were applied for the steel meshes (P=0.787) .The preliminary investigations ...


  • The Magnetic Duo

    (From Resource Recycling) The combination of high gradient magnetic separation using rare earth roll magnets and eddy current separation has proved to reliably remove aluminum flakes mixed with PET. Recycling of plastic beverage containers made from polyethylene terephthalate (PET) has been a growth industry for the past two decades. Recycled PET can be used in such diverse products as ...

  • Utilizing a Multiple Metal Detector Array for Locating Anomalies Indicative of Ferrous and Non-Ferrous OE/UXO

    ABSTRACT An array of three Geonics Limited EM61-MK2 metal detectors was utilized to identify subsurface metallic anomalies at the Mare Island Naval Shipyard in Vallejo, California. The goal of the 120-acre survey was to locate anomalies indicative of ferrous and nonferrous ordnance and explosives/unexploded ordnance (OE/UXO) in dredge pond berms with particular attention to 20 mm high explosive ...
