Systems and methods for separating paramagnetic material in wellbore return fluid. A quadrupole magnet system is disposed along conduit so that a paramagnetic field is symmetrically formed about a central axis of the conduit. A wellbore return fluid containing paramagnetic material is directed through the conduit. The paramagnetic field drives the paramagnetic material outward towards the perimeter of the conduit, thereby concentrating fluid with little or no paramagnetic material along the central axis of the conduit. An outlet is disposed along the flow path of a portion of the concentrated fluid. In some embodiments, the outlet is positioned along the central axis, while in other embodiments, the outlet is positioned along the conduit wall. The paramagnetic material may be weighting material used to prepare drilling mud.
