    Magnetic Separation - an overview | ScienceDirect

    Magnetic filtration has been applied in place of lime treatment by Feng and coworkers (2000).Ultrafine magnetic particles are used as magnetic seeds. At a dosage of 0.5 g/L magnetite, all fine precipitate flocs can be rendered strongly magnetic. The mine water is treated with hydrogen peroxide (to oxidize ferrous iron and manganese), followed by the addition of

    How Does Metal Sensing, Separation, and Sorting

    Metal sensing is the first step a recycler must take. Bulk recyclers take in shredded cars, extra materials from construction, and waste from demolition sites. From this, they have to detect the different types of metal in a massive mixture of plastics, glass, rubber, and other components. Magnets can be used to remove any steel, iron or other
