Abstract

This invention relates to a continuous or batch centrifugation solid-liquid separation process comprising simultaneously subjecting the solid-liquid mixture to localized magnetic field gradients and the centrifugation and to improved centrifugation solid-liquid separation processes wherein the improvement comprises simultaneously subjecting the solid-liquid mixture to a homogeneous magnetic field, a magnetic field gradient or both prior to and/or during the centrifugation.
