The aim of this study was to determine the appropriate bridging liquid for lignites at selective agglomeration. Kerosene, diesel-oil, fuel-oil, spindle oil, heavy neutral, bright stock, light neutral and various surface active components were used. The best results were obtained with a mixture of 70% fuel-oil + 15% Acorga M5640 + 15% 2-ethyl hexanol or other alcohol type of reagents. It was determined that a clean coal having an ash content of 17% with a combustible recovery more than 90%, was produced from a coal with an ash content of 35.27%. (C) 1998 Elsevier Science Ltd.
