The entrainment of fine quartz particles into magnetite coagulates in a uniform magnetic field was studied through in situ observation using a video microscope. It is shown that the mechanisms for this entrainment are attributed to the magnetic coagulation of locked quartz–magnetite particles with free magnetite particles, the entrainment of free quartz particles into magnetite pearl chains, and wrapping of magnetite circular chains round free and locked quartz particles.
Graphical abstractMagnetite circular chains wrapped round free and locked quartz particles as gradual increase of field intensity. While the circle shrunk at 0.011 T, the quartz particles were entrained into coagulates.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► In situ observation of magnetic coagulation of magnetite fines. ► Mechanisms for quartz fines entrained in magnetite coagulates. ► Effect of magnetic field-intensity on entrainment of quartz fines.
