ABSTRACT:
Method for improving production rates during magnetic separation of magnetically attractable particles dispersed in a fluid carrier, as for example during separation of weakly magnetic discoloring contaminants dispersed in a clay slurry. The dispersion is passed through a ferromagnetic filamentatious matrix within a canister disposed in a magnetic field. The matrix is part of a magnetic separator system characterized by a separation parameter p, where p is a function of the geometry and magnetic and electrical properties of the separating apparatus; and of the rheological and magnetic properties of the dispersion. By determinatively adjusting the packing density of the matrix in the canister, and/or by utilizing appropriate solids content in the slurry, production rate is controlled or optimized for a given brightness increase in the clay.
