摘要：
The effectiveness of oil agglomeration with a vegetable oil, in removing As, Be, Co, Cr, Hg, Mn, Mo, Ni, Pb, Sb and U elements, from a coal fine waste was evaluated using different sunflower oil concentrations. From the results it was concluded that agglomeration with low concentrations of vegetable oils is an effective process for recovering combustible coal from coal fine wastes, not only in terms of high ash rejection and mineral matter recovery but also in the reduction of toxic trace elements emissions.
