The present study was undertaken to determine the effect of recovery sieve size on the performance of oil agglomeration of coal. An oxidized fine coal sample was subjected to oil agglomeration process. Combustible recoveries and ash-sulphur rejections were investigated. 72.90% of ash, 90.90% of pyritic sulphur, and 87.75% of sulphate sulphur was removed from the coal with combustible recovery of 76.53%. While increase in recovery sieve size had positive effect on rejections of ash and sulphur, it reduced combustible recovery sharply. It was concluded that use of recovery sieve whose size is higher than top feed size was not feasible at applied test conditions.
