Multiple matrix assembly and matrix unit for magnetic separator with simplified sealing

A multiple matrix assembly for a magnetic separator comprising:

• a container;
• a plurality of magnetic matrices each having a feed area, a collection area on opposite longitudinal ends, and a peripheral portion and being arranged in a longitudinal stacked array in said container with like areas of adjacent matrices facing each other;
• each of said matrices having its longitudinal ends spaced from adjacent said matrices, to form common, alternate feed and collection areas;
• the peripheral portion of each of said matrices being sealingly engaged with said container;
• and inlet means and outlet means for feeding to and collecting from said common feed and collection areas.

A matrix unit for a multiple matrix assembly for a magnetic separator in which the matrix units are arranged longitudinally in a stacked array comprising:

• a magnetic matrix having first and second areas on opposite longitudinal ends of said matrix transverse to the longitudinal axis of said matrix and to the longitudinal flow through it, and having a peripheral portion surrounding it and extending longitudinally between said first and second areas;
• and
• an open receptacle for housing said matrix and having a transverse member proximate to and coextensive with only one of said first and second areas and a peripheral member extending longitudinally from said transverse member along and sealingly engaged with said peripheral portion of said matrix;
• said transverse member including at least two ports for accommodating inlet and outlet means and a sleeve extending from said transverse member about each port through one or more matrices, at least one sleeve extending in each direction.
