  • Understanding Challenging Applications for Improved Metal Detection

    In the food industry, certain products can act like metal contaminants, a phenomenon known as ‘product effect.’ This is where the type of product being inspected can hinder the ability of inspection technology to correctly identify metal. At best this can lead to unacceptable false reject levels, at worst it can result in metal contaminated product leaving the production facility. ...

  • Visible light induced photocatalytic degradation of rhodamine B by magnetic bentonite

    The photocatalytic activity of magnetic bentonite, Fe3O4 nanoparticles decorated Al-pillared bentonite (Fe3O4/Al-B), for the degradation of rhodamine B (RhB) in the presence of H2O2 under visible light (VL) was evaluated. The effects of different reaction parameters such as catalyst dose, dye concentration and externally added ...

  • Decrease of Pseudomonas aeruginosa biofilm formation by food waste materials

    The formation of bacterial biofilm on various surfaces has significant negative economic effects. The aim of this study was to find a simple procedure to decrease the Pseudomonas aeruginosa biofilm formation in a water environment by using different food waste biological materials as signal molecule adsorbents. The selected biomaterials did not reduce the cell growth but affected biofilm ...

  • 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 ...

  • Magnetic Separation Myths 5 of 10 Magnetic Separators Lose Their Magnetic Strength Over Time

    It is a question that gets frequently asked: When will the Magnetic Separator start losing its magnetic strength? In a perfect world, a magnetic separator should not lose any magnetic strength. However, there are occasions when external factors will affect the magnetic strength and these include: The use of bonded Rare Earth Magnets. ...


  • Recovery of lead from bullet berms on shooting ranges using Ekokem`s method - Case Study

    Ekokem has developed a method by which it is able to separate bullets from berm soil. The method used for separation is based on the electromagnetic properties of lead and on sensor technology. A considerable number of bullets accumulate on shooting ranges every year. It is important to remove them from outdoor shooting ranges as the lead they contain can leach into the soil, where it ...

  • Magnetic Separation Myths 1 of 10 – Always Use the Strongest Magnet

    Strongest is always best, or is it? Commonly, companies will call and request a quote for the strongest magnet. But do they actually need a magnetic separator with the highest magnetic pulling power? The strongest magnetic fields are produced by superconductors and are used in industrial and medical applications.  However, their use in industry is very specific due to the high capital ...


  • Vulcanis Maximise Steel Can Recovery with a Bunting Cross Belt Overband Magnet

    Vulcanis has designed and built a new recycling plant to receive and recover steel and aluminium cans in Barking, UK, and purchased a Cross Belt Overband Magnet for steel can recovery from Bunting Magnetics Europe Ltd. Presently, consumers in the UK use approximately 13 billion steel cans and 50 billion aluminium cans per annum and recycling rates are 61% for steel (Tata 2014) and 57% ...

  • 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 ...

  • Things You Should Learn About Neodymium Magnets

    A neodymium magnet boasts many applications in various industries. It is currently the leading permanent magnet on earth. Without this magnet the world would put pressure on scientists to find a matching alternative. But this is unlikely to happen any time soon as China mines ninety-seven percent of world’s neodymium. Perhaps more mines will be re-opened in the US, as neodymium magnets are ...

  • 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 ...
