The increment in generation of large quantity of fines while mining and beneficiation has led to the serious environmental issues. In this present study, non-edible oil such as Karanja oil was used as bridging liquid to recover coal fines from washery tailings sample, which were discarded while beneficiation process. The coal washery tailings sample was collected from Dhanbad, Jharkhand, with high ash content of 52.74%. The effects of pulp density, oil dosage, and agglomeration time were investigated. From the experimentation, it was found that ash rejection was in the range of 60.90% to 74.96% and organic matter recovery was in the range of 61.14% to 84.77%.
