Abstract The breakage parameters of phosphate ore were determined by batch first-ordering grinding studies in a laboratory ball mill according to the Austin, Klimpel, and Luckie procedures. The results were scaled to five larger mills of 0.56, 0.82, 3.36, 4.41, and 5 m in diameter assuming equilibrium ball charges for the full-scale mills.
