The aim of process calculations is to evaluate the performance of minerals and coal processing operations in terms of efficiency of the operation, grade of the final products and recovery of the required constituents. To meet these requirements, indepth detailed calculations are illustrated in this ...
F. Mir 504 On the basis of specific assumption that recovery is an incessant function of growing fractional weight of feed coal floated, the recovery curves for non ash and ash materials has been drawn for the calculation of washability.

This test method describes procedures for determining the washability characteristics of coarsecoal fractions and finecoal fractions. Each sample being tested can have more than one coarsecoal size fraction and more than one finecoal size fraction (see Annex A1). Each such size fraction has an upper size limit and a lower size limit ...
Washability curve data is based on bench 11 from the Grootegeluk formation (Faure et al., 1996). models for a coal cleaning system to be used for computational calculations for coal washability. The Mcurve is a simple curve that can generally fit a conic section equation which typically represents a washability curve. Bowen
