Abstract
A method for effecting magnetic separation of magnetically attractable particles dispersed in a fluid carrier, as for example 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 determinately setting the controllable parameters associated with the aforementioned properties which affect p, a desired attenuation in the population of contaminant species is achieved. Optimized apparatus configurations are also disclosed, which configurations are based upon the discovered relationships.
