Abstract. This paper examines the bauxite particle size requirements for the Bayer Process. A closed circuit Semi-Autogenous Grinding (SAG) mill with a hydrocyclone is considered to be the most suitable for a high bauxite throughput operation. SAG Mills do more than just grind, they tumble, separate, and size classify the feed through multiple
