Abstract

Method for the wet dynamic separation of a suspension in liquid phase, comprising microparticles comprising a magnetic material and a liquid medium in which said microparticles are in suspension, in which method: a) the suspension is confined in a chamber having a volume defined by at least two dimensions, for example length and depth; b) at least one plurality of elementary magnetic fields is set up, these magnetic fields being distributed in a 'Halbach semi-configuration', whose respective ends facing the chamber generate a vector sum of said elementary magnetic fields, corresponding to a magnetic capture field passing through said chamber and exerting a magnetic attraction on the microparticles, and whose opposite respective ends generate no magnetic field; and c) said capture magnetic field is generated, whereby a solid phase enriched with microparticles is captured in said chamber, and a liquid phase depleted in microparticles is extracted from said chamber.
