The magnetic collection of fine particles requires a high-intensity, high-gradient magnetic field. An electromagnetic matrix-type separator, referred to as a magnet filter, has proven to be the most effective method of separation. This type of separator utilizes a high-intensity electromagnet and a flux-converging matrix. The matrix amplifies ...
