2019-11-1  Particle size distribution analysis. The particle size distribution (PSD) of the two coals and pyrite samples were determined to establish the slime deportment with particle size, and to investigate the effect of particle size on desulphurization of coal. The PSD was determined by using a Mastersizer 3000 laser particle sizer (Malvern, UK).
