Result of the pilot tests on particle segregation by elutriation

The method used to assess the segregation of particles by elutriation was published in 2002 (Technical Datasheet No. 41). In short, this method consists in comparing the concentration of tracer above and below a sample that has been dropped in a column. The elutriation ratio defined by this method ranges from – 200 to + 200; a null ratio indicates the stability of the traced product. In 2004, it was demonstrated that, to a certain extent, this method could be used to predict segregation.
