Abstract
A new device designed for wet magnetic separation-magnetic hydrocyclone-allows separating magnetic fraction from a fast and curved flow of pulp. The advantages of the magnetic hydrocyclone are the high specific output and the design simplicity which governs reliability of the device. The pattern of calculation of the magnetic hydrocyclonage performance represents an estimation of separability of magnetic fraction depending on the device geometry, variation in the magnetic field parameters, flow velocity and the physical parameters of the particles. The processing performance from calculations is compared with the results of the magnetic hydrocyclone testing. The proposed device is recommended to be included in the processing flow chart for ferruginous quartzite and other types of ore with the pronounced magnetic properties. Inclusion a magnetic system allowing higher magnetic induction up to 5-10 Tl in the flow chart makes it possible to extract weakly magnetic minerals.
