The screen analysis of 0.75kg of a mineral sample is shown in the following table. Neglecting the pan and assuming the sphericity =0.75, shape factor =2.0, and density of the mineral =2600 kg/m3, calculate : a) The unknown mass fraction retained on top of 200 mesh. b) The volume - mean diameter Dv. c) The mass - mean diameter Dw. d) The number of particles for the 200 mesh increment N200. e) The surface area for the 200 mesh increment A200. f) Make the same calculations considering 2.75% loss to Pan
