Elutriation apparatus and process using apparatus comprising an upper and a lower member separated by a restricted intermediate cross-section member wherein the lower member has a lesser cross section than the upper member. The process is carried out by operating the lower member as a dispersed suspension (known per se) elutriation apparatus and by operating the upper member as a dense fluidized bed (known per se) elutriation apparatus with the intermediate member causing an increase in the velocity, of at least 1.2 times, of the elutriant passing therethrough from the lower to the upper members.
