Magnetic cyclone and method of operating it

摘要

One aspect of the invention concerns a cyclone which has a cyclone vessel having an underflow and an overflow and an inlet for feed material. Means are provided to generate a vertically oriented magnetic field in the cyclone vessel for the purposes of controlling the operation thereof. Another aspect of the invention concerns a method of operating a cyclone vessel in which at least the density differential achieved by the cyclone is controlled by means of a vertically oriented magnetic field.
