Abstract:
A high gradient magnetic separator including a separation zone comprising: a matrix of sets of parallel magnetic wires arranged in rows of parallel planes with a channel extending in each row between adjacent sets of parallel wires and having non-magnetic walls for conducting a fluid including magnetic particles through said matrix in parallel with said matrix of wires, a magnetizing structure disposed adjacent said matrix for generating a magnetic field with field lines extending essentially normal to said parallel planes formed by said sets of wires and channels arranged in said rows, and separating walls disposed in parts of said channels ahead of an end area of the magnetic field generated in said matrix adjacent the flow exit area of said channels from said matrix, said separating walls extending parallel to said planes and normal to said magnetic field lines and forming partial flow channels for receiving partial fluid flows with magnetic particle-enriched flow volumes and, respectively, magnetic particle-depleted flow volumes.
