  • Case study: OCC recovery

    Challenge A waste recycling facility was looking to recover mainly OCC (Old Corrugated Cardboard) from his waste stream. They saw the value in recovering this product, but were presently manually sorting the material off of the floor on a daily basis. Even with floor sorting, the customer was able to recover in the neighborhood of 10-12 bales per day. Approach ...

  • Equilibrium adsorption isotherm of U(VI) at pH 4 and pH 5 onto synthetic magnetite nanoparticles

    The adsorption features of synthetic magnetite nanoparticles have been investigated for removal of uranyl ions from nitric solutions. These magnetic nanoparticles can be used to adsorb contaminants in wastewater and can subsequently be removed from the medium by a magnetic process because of their superparamagnetic behaviour. The magnetite nanoparticles were synthesised by simultaneous ...

  • 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 ...

  • Spin-transfer effect and its use in spintronic components

    Spin-electronics is a very rapidly expanding area of R&D which merges magnetism and electronics (Nobel Prize 2007). Since the discovery of giant magnetoresistance in 1988, several breakthroughs have further boosted this field (spin-valves 1990, tunnel magnetoresistance 1995, spin transfer 1996, voltage controlled magnetic properties 2004). The phenomenon of spin-transfer is particularly ...

  • Recovery of sillimanite from beach sand of Chhatrapur, Orissa, India and its thermal treatment for refractory application

    Beach sands of Chhatrapur, Orissa, India comprise about 18% of heavy minerals, mixed with light minerals like quartz and feldspar. Sillimanite, which has refractory applications, accounts for 8% of these heavy minerals. Sillimanite was separated from garnet, monazite, zircon, rutile, ilmenite, magnetite, hematite and pseudo-rutile by combination of spiral, Wet High-Intensity Magnetic Separation ...

  • 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, ...

  • 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. ...

  • Variable temperature magnetic force microscopy of La2/3Sr1/3MnO3 thin films grown on (LaAlO3)0.3(Sr2AlTaO6)0.7 (LSAT) substrates

    The surface magnetic domain patterns of a La2/3Sr1/3MnO3 film grown on a LSAT (001) substrate, where LSAT stands for (LaAlO3)0.3(Sr2AlTaO6)0.7, were observed by magnetic force microscopy (MFM) as a function of the temperature in the 300?360 K range at its remanent state. Magnetic stripe domains showing an up and down magnetic configuration were observed, thus indicating the existence of a small ...

  • 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 ...

  • Mesoscopic Kondo effects in nanoscale systems

    A few selected topics on the Kondo effects in mesoscopic systems have been reviewed. Included are the effects of the competition of the spin polarisation and the superconductivity with the Kondo correlation in quantum dots coupled to ferromagnetic and superconducting leads, respectively, and the SU(4) Kondo effects due to the orbital degeneracy in vertical quantum dots, carbon nanotube quantum ...

  • 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 ...

  • Crossflow Membrane Filtration High-Purity Water Systems

    INTRODUCTION As the electronics industry continues to provide us with such products as high resolution television, notebook size portable computers and cars with automatic navigation systems, it becomes necessary to produce semiconductors with finer device geometries to allow for efficient placement of more circuits per a given area. This requires increased control of a semiconductor's material ...
