In this study, comparison of performance of different oils, in the cleaning of Zonguldak coal, by oil agglomeration was investigated. The feed coal was agglomerated with both classic oils (kerosene, diesel and fuel) used for the coal agglomeration and lubricating oils (spindle, heavy neutral and bright stock) over a wide range of oil concentrations. The performance of the agglomeration process was evaluated by the combustible recovery, ash rejection and efficiency index. It was found that the combustible recovery and ash rejection changed, depending on the type and concentration of oil. The oils were tested for combustible recovery and maximum combustible recovery was obtained on using kerosene. It was found that kerosene, diesel-oil, spindle oil and heavy neutral were suitable for the agglomeration of Zonguldak coal. On considering the efficiency index values, the best results were obtained with heavy neutral. Consequently, it was shown that heavy neutral and spindle oil can be used as alternative oils instead of classic oils for the cleaning of Zonguldak coal by the oil agglomeration.
