ABSTRACT:
The method of concentrating magnetic ore consists of forcing a fluid medium to flow along guides having curved and rectilinear portions; and directing the flow by a pulsating magnetic flux, so that the heavy magnetic particles are forced towards the outer side of the guides. Less heavy particles of the nonmagnetic fraction are washed away by the flow of a fluid medium. In the curved portions of the guides, the magnetic flux coincides in direction with the centrifugal force; in the rectilinear portions of the guides, there is no centrifugal force and the magnetic flux is directed at right angles to the flow of the ore to be concentrated. The magnetic centrifugal separator includes and air-tight housing having curved portions alternating with rectilinear portions. Sources of magnetic flux are located on these portions of the housing. Means are provided to cause the magnetic flux to pulsate.
