Apparatus and process for separating particles of wollastonite ore and other aspect ratio materials into a relatively high aspect ratio constituent and a relatively low aspect ratio constituent includes an initial step of either size reducing ( 2 ) the material into particles of the aspect ratio material having a size less than a preselected maximum size or alternatively providing such particles of the aspect ratio material. The particles of the aspect ratio material are then separated ( 4 ) into a plurality of particle streams based on particle size such that each particle stream is formed substantially from particles within a particular range of particle sizes. Then, the particles in at least one particle stream are sorted ( 6 ) based on particle shape into the relatively high and relatively low aspect ratio constituents. The particle separation step ( 4 ) is preferably performed using mesh screening apparatus. The shape sorting step ( 6 ) is preferably performed using apparatus for separating grain.
