ABSTRACT:
A separation apparatus and method for use in separating magnetic material from non-magnetic material that includes the use of a magnetic grid, e.g., a permanently magnetic grid, which defines a plurality of openings. The grid assists in preventing magnetic material from being transported to an overflow.
