     · As expected the grain size distribution from the 2D cross-sectional data is finer than the actual three-dimensional size distribution. The P80 (or the screen size which 80 of the mass passes) is a parameter commonly used to summarise grain size data in this case the 2D data give a P80 value of 250 μm which compares with a P80 of 320 μm

    The AG mill operates in closed circuit with a pebble crushing circuit and primary hydrocyclones. The hydrocyclone overflow product at a particle size distribution of 80 per cent passing around 110 microns (P80 = 110µm) is treated in two vertical ball mills ("Vertimills") operating in closed circuit with a second bank of hydrocyclones.
