“…Magnetic separation processes for ferromagnetic materials or ferrous particles have been used extensively in the past [1][2][3]. The use of very fine magnetic matrix elements to improve the removal of magnetic particles from suspensions has been steadily increased in recent years [4][5][6][7]. This technique has also been successfully applied in solid waste separation and recycling, ultra purification of many fine chemicals, nano and biotechnology, etc [8][9][10][11][12][13].…”

Liqun Luo, Anh V Nguyen / A review of principles and applications of magnetic flocculation and separation of ultrafine magnetic particles 2 H I G H L I G H T S • The principles of magnetic separation have been critically reviewed; • Both external and interparticle forces for ultrafine particles are reviewed and compared; • Suspensions stability of the particles factors are described and analyzed; • Various modeling of magnetic flocculation are introduced and some of the applications are illustrated. Liqun Luo, Anh V Nguyen / A review of principles and applications of magnetic flocculation and separation of ultrafine magnetic particles 3 A B S T R A C T Magnetic separation has been used in industries to concentrate or remove magnetic minerals/particles for many years. The separation of ultrafine magnetic particles is significantly influenced by aggregation between particles due to various external and interparticle forces, such as gravity, magnetic attraction, van der Waals, electrical double-layer, hydrodynamic, and Brownian diffusion forces. This review focuses on the principles of the magnetic flocculation and separation of micrometer-sized particles in solution. Potential energies between particles are linked to the particle aggregation (i.e. stability), sedimentation and dispersion in applied magnetic fields. Prediction and control of magnetic flocculation are achieved by simulating particle motions around the surface of the magnetic separators using various mathematical models, with some large-scale applications of magnetic flocculation are being demonstrated.

A current subject of research is the application of magnetic effects for the detachment of accumulated particles of fibrous collectors in gas particle separation. Initial studies have already shown the magnetically induced detachment behavior of a compact particle structure after a single deflection from a single fiber. In this study, the detachment behavior of particle structures with different morphologies from a single fiber is investigated as a function of the particle loading stage on the fiber, the external magnetic flux density, the inflow velocity and the number of regenerations of the fiber for a certain parameter range. Diffusive and more compact particle structures with non-magnetic properties are deposited on the magnetizable single fiber. By applying an external magnetic field, the fiber is magnetized and experiences a torsional moment. The deposited particle structures on the fiber are detached by the acceleration forces. The detachment of the particle structures is observed using a high-speed camera and the image sequences are analyzed. By determining the projection area before and after the fiber deflection, a degree of regeneration is calculated. With magnetic-induced regeneration, high degrees of regeneration close to 100% can be achieved. Repetitive fiber deflections improve the detachment of the particle structures. The magnetic-induced regeneration is suitable for applications where flow reversal is not possible and can be performed either online or offline. Due to the gentle regeneration, fewer emissions are produced on the clean gas side than, for example, with jet pulse cleaning. It makes it easier to achieve emission limits and simplifies product recovery.
