Abstract
Abstract A multiple matrix assembly for a magnetic separator comprising a plurality, M, of magnetic matrices arranged in a longitudinal stacked array each matrix being fed by a number, p, of inlets and having its product collected by a number, p, of outlets; at least one partition means including a transverse member between each adjacent pair of matrices; a container for receiving the matrices and the partition means; each partition means and the longitudinal ends of the container including a number of ports, P, equal to p × M, arranged in M sectors with p ports per sector, the pattern of ports being the same in each sector; each matrix having on each longitudinal end, p sections of approximately equal area and P port positions corresponding to the P ports in the partition means, each of p port positions being located at approximately the center of each of the p sections, and being defined as through-put positions and the remaining P - p port positions being through-holes penetrating the matrix; each of the p through-put positions in any particular sector having associated with it M - 1 through-holes at a corresponding location one in each of the other M - 1 sectors.
