  • Application of particle size distribution analysis in ...

    01/03/2007  Thus the mass of a single coal reject particle under each fraction was given by Eq. : (10) w = 4 3 π r 3 × 2.19 where r = L / 2. Ideally, the particles would mean the pyrite particles. However, in the present study we refer to particle size of the whole material i.e. the coarse reject.
