The application provides an apparatus for removing ferrous particles from an oil or gas process liquid or slurry and a method of use. The apparatus has a first inner cylindrical sheath and a second outer cylindrical sheath arranged concentrically on a longitudinal axis to create an annular volume. A helical screw flight on the first or second cylindrical sheaths extends across the annular volume, and a magnet assembly extends along the longitudinal axis, such that ferrous particles are attracted to a surface of the annular volume. The apparatus has an inlet a discharge outlet, and a ferrous particle collection location. The screw flight and the cylindrical sheath operable to rotate with respect to the magnet assembly to convey particles to the collection location. The apparatus includes a retaining surface to retain collected particles.
