    摘要: A method of separating predetermined non-magnetic electrically conductive items from a flow of non-magnetic electrically conductive materials containing such items comprises the steps of passing the flow of materials adjacent to electromagnetic field (3) generating apparatus; subjecting the materials to the action of a fluid (6) whilst the flow of materials is adjacent to the electromagnetic field generating apparatus; controlling the flux field generated by the apparatus such as to create electrical current within the predetermined electrically conductive items which react with the generated electromagnetic flux field causing the creation of a directional force upon the predetermined items, in association with the subjection thereof to the fluid (6), such as to move only the predetermined electrically conductive items out of and away from the flow of material in a predetermined direction for a predetermined distance (4).
    In another aspect the method comprises passing the flow of materials adjacent to a linear induction motor (3); controlling the flux field generated by the linear induction motor and providing a pulse of such field by switching on and off the linear induction motor at a frequency lower than the supply frequency such as to create consequential pulsed electric currents within the predetermined electrically conductive items which react with the pulsed generated electromagnetic flux field causing the creation of an intermittent force upon the predetermined items such as to move only the predetermined electrically conductive items out of and away from the flow of materials.
