Mineral matters in six coal samples from different localities were classified into four groups; A) mainly quartz, B) pyrite, C) mainly clay minerals and D) iron oxide. The size distribution and liberation degree of each group mineral were measured using an image analyzer equipped with a microscope. Minerals of A, B and D groups were easily liberated from coal by grinding. On the other hand, C group minerals were easily crushed but often remained and attached to the coal particles. Based on the results measured and observed, a liberation model was proposed to evaluate the liberation behaviour of the minerals. Using the model, liberation degrees were calculated and the values agreed well with the measured values.
