<p>The present disclosure relates to a process for the treatment of a paper pulp, wherein, in a first step, a composition of particles of lamellar silicate is added to said paper pulp, and in a second step, said paper pulp is passed through a centrifugation device chosen so as to separate a composition loaded with contaminants from said paper pulp, characterized in that said composition of particles of lamellar silicate comprises at least 20 wt.% of a first fraction of particles of lamellar silicate, named fine fraction, whose particles of lamellar silicate have an equivalent spherical diameter of between 0.5 µm and 7 µm, and at least 20 wt.% of a second fraction of particles of lamellar silicate, named coarse fraction, whose particles of lamellar silicate have an equivalent spherical diameter of between 7 µm and 30 µm.</p> |
