Modern mechanized mining techniques produce enormous quantities of coal fines. Reagents regime (i.e. reagents usage and reagent type) is an important fundamental factor in the process of recovering and dashing of ultra-fine coals (coal fines). The other factors that are crucial for recovery and the purity of the final product obtained is the nature of the particle size of the solids as well as the adsorption of the reagent on the solid particles surface among others. Coal concentrators and mills have embark on the strategy of establishment fine coal benefaction reagents which are not only cheap but effective and efficient. In this study, the effects of both the Flomin C 9202 and Emulsified light diesel oil are investigated in regards to their performance on the combustible recovery as well as the ash remaining in the clean coal product. The study, further involves grinding the coal sample to obtain the fines sizes, flocculate the fines to get the agglomerates and finally float them, what is commonly referred to as Agglo-flotation. The results for both Flomin C 9202 and emulsified light diesel oil were analyzed and after obtaining the best collector (which in this case was Flomin C 9202) then the flowsheet was there after determined. The batch tests for collector determination showed that the Flomin C 9202 outperformed the emulsified diesel oil, and after conducting two stages flowsheet with the collector (Flomin C9202), the ash content was reduced from 22.78%(original coal sample) to 7.91% while the combustible recovery increased from 77.44% (original coal sample) to 92.85%.
