ABSTRACT:
An improved air jig apparatus and method is disclosed in which a dry magnetic separator is used to separate paramagnetic and ferromagnetic minerals from the dust component of coal cleaned with the air jig. The cleaned product of the dry magnetic separator is combined with the cleaned product of the air jig thereby improving both the quality and the quantity of the unmodified air jig product. The dry magnetic separator may be of a variety of types including but not limited to separators made from permanent magnets, electromagnets, and superconducting magnets, each of which may also employ triboelectric and/or aerodynamic means to enhance the separation of the dust material.
