Abstract
A mixture of ferromagnetic material and non-ferromagnetic material is separated by first conveying the mixture to an inlet of a tubular member. An electro-magnetic field is then sequentially energized along the length of the tubular member from the inlet to an outlet to attract the ferromagnetic material away from the mixture into the inlet and impel the separated ferromagnetic material through the tubular member for subsequent discharge through the outlet.
