Vortex magnetic separation (VMS)

Vortex magnetic separation (VMS)
Vortex magnetic separation (VMS)

This thesis reports an investigation into a new technique of magnetic separation which has been named vortex magnetic separation (VMS). A study into mechanical entrapment in HGMS was carried out. It was found that the upstream-side magnetic capture, the usual case for HGMS in present practice, invariably causes the mechanical entrapment which reduces the selectivity of the HGMS process and prevents HGMS from wider commercial application. The new technique, vortex magnetic separation, elegantly solves the selectivity problem of HGMS. Its mechanism and the main performance parameters were studied in detail, with particular emphasis towards the secondary concentration process in VMS and its dependence on the boundary layer around the matrix. A new method, the cryogenic cell method, was designed and successfully used to demonstrate the high selectivity of VMS.

The new technique, vortex magnetic separation, elegantly solves the selectivity problem of HGMS. Its mechanism and the main performance parameters were studied in detail, with particular emphasis towards the secondary concentration process in VMS and its dependence on the boundary layer around the matrix. A new method, the cryogenic cell method, was designed and successfully used to demonstrate the high selectivity of VMS.
