ABSTRACT:
The invention provides a method of separating predetermined non-magnetic electrically conductive items from a flow of non-magnetic electrically conductive materials containing such items and other non-magnetic electrically conductive materials comprising the steps of passing the flow of materials adjacent to electromagnetic field generating apparatus; controlling the flux field generated by the apparatus such as to create electrical currents 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 such as to move only the predetermined electrically conductive items out of and away from the flow of material.
