20110094943 | MAGNETIC SEPARATOR - There are provided devices, systems and processes to treat slurries that include magnetic and nonmagnetic particles suspended in water in such a fashion as to separate certain valuable elements and/or minerals from less valuable minerals or elements. A high intensity magnetic separator includes at least one large rotatable turntable that defines at least one circular channel therethrough in which a matrix material is positioned. The turntable is configured to rotate in a generally horizontal plane about a generally vertical virtual axis, causing the at least one circular channel to rotate through a plurality of intermittent magnetic and nonmagnetic zones generated by a plurality of permanent magnet members. A treatment slurry is directed into the channel or channels in one or more of the magnetic zones as the turntable rotates. A tailings fraction passes through the channel or channels in a generally downward direction in the magnetic zones and is collected in tailings launders. Magnetic particles are attracted to the matrix material in the magnetic zones and remain in the channel until it passes into an adjacent nonmagnetic zone, where the magnetic particles are washed form the channel into concentrate launders. | 04-28-2011 |
20120325726 | IRON ORE SEPARATION DEVICE - Slurries of magnetic and nonmagnetic particles in water are treated in a high intensity magnetic separator including at least one turntable that defines at least one circular channel therethrough in which a matrix material is positioned. Rotation of the turntable in a generally horizontal plane about a generally vertical virtual axis causes the circular channel(s) to rotate through a plurality of magnetic and nonmagnetic zones generated by magnet members. Treatment slurry is directed into the channel(s) in one or more of the magnetic zones as the turntable rotates. A tailings fraction passing through the channel(s) in a generally downward direction in the magnetic zones is collected in tailings launders. Magnetic particles attracted to the matrix material in the magnetic zones remain in the channel(s) until they pass into an adjacent nonmagnetic zone, where the magnetic particles are washed from the channel(s) into concentrate launders. | 12-27-2012 |
