    Magnetic nanoparticles (MNPs) which exhibit magnetic and catalytic bifunctionalities have been widely accepted as one of the most promising nanoagents used in water purification processes. However, due to the magnetic dipole-dipole interaction, MNPs can easily lose their colloidal stability and tend to agglomerate. Thus, it is necessary to enhance their colloidal stability in order to maintain

  • A Preliminary Investigation into Separating Performance

    Abstract: The matrix is the agglomeration carrier of magnetic mineral particles in high-gradient magnetic separation (HGMS). Its structural parameters have a great influence on the distribution of the magnetic field in the separation space, and therefore affect the separation effect. This paper

  • Study on Influence of Residual Magnetite in Panzhihua

    Jan 01, 2011· Magnetic separation tailings mainly contained ilmenite, but there was still a small quantity of titano-magnetite. Magnetic agglomeration of titano- magnetite occured because of existentence of remanence and pre-flotation grinding. It was found that titano- magnetite presented more optimal floatability than ilmenite.

    Luzheng Chen, Dahe Xiong, in Progress in Filtration and Separation, 2015. 2.1.4 Screen Magnetic Separator. Screen magnetic separator presents another magnetic technique for the cleaning of strongly magnetic minerals such as magnetite, based on the principle of magnetic agglomeration (Li, 2005).

  • Inhibiting the amine flotation of magnetite through

    Apr 01, 2018· Magnetic energy has been applied to flotation in order to diminish the floatability of paramagnetic and ferrimagnetic minerals. Yousef et al., (1971) used the magnetic field generated by the coils of a Davis tube equipment to impair the flotation of magnetite while floating chromite.

  • Neutron Diffraction Analysis and Electromagnetic

    Sep 28, 2018· As shown in Fig. 2, the powders with partially agglomeration are observed. In this study, it is difficult to quantitatively analyze the agglomeration of the nano-particles of the powders. However, it is clear that the powders with less than 50 nm in size are obtained by magnetic separation with an ultrasonic floating-agitation classification.
