<p>An improved magnetic separator arrangement (30) is provided. One major improvement relates to modifications facilitating utilization of relatively dense and tightly packed matrix material (50) within races (48), through which a slurry of ore material passes during separation. The tightly packed matrix material (50) is accommodated through utilization of flexible race walls (60, 61), and compression (220, 221) and expansion (185, 207) mechanisms selectively operable to facilitate separation. A cover mechanism (275) inhibits water flow turbulence, during an initial setting up of a magnetic field to entrap magnetic material within the matrix element of each race. A preferred retainer mechanism (300) is provided which facilitates mounting of flap members (270) for use in association with a cover mechanism, as well as retention of the matrix material in a desired position. In a preferred embodiment, the previous features are incorporated into a system fed with an ore material from an inner portion of a circular race, i.e. the center of a rotating drum (31).</p> |
