Process for separating cellulosic pulp fibers into fractions endowed with different characteristics, capable of using one of the fiber fractions or a combination of fiber fractions to manufacture a sheet of paper, characterized in that they buy from defiberizing wood until converting it into cellulosic pulp as an aqueous mixture containing a heterogeneous mixture of spring and summer wood fibers and separating the mixture into fiber fractions containing, respectively, predominantly spring and summer wood fibers, subjecting the mixture to forces that cause the fibers that have a apparent relative density, comparatively lower, are separated from the fibers that have a comparatively higher apparent relative density.
