Abstract
A magnetic separator apparatus for use in separating magnetic material from a mixture of at least magnetic material and a liquid includes an endless belt defining a channel. A portion of the endless belt is movable up an incline relative to horizontal through a separation zone. The endless belt includes an endless base section having a predetermined length and first and second sidewalls extending from the endless base section along the entire predetermined length thereof. The endless base section and the first and second sidewalls define the channel wherein the mixture is received. Further, the apparatus includes a ferromagnetic collection matrix positioned in the channel and one or more magnets positioned for generating a magnetic field in the separation zone. A method for use in separating magnetic material from a mixture using such an apparatus is also provided.
