Therefore, the purpose of this study was to remove the sulfur and ash from coal using various types of indigenous bacteria by the biomining method. The current study used coal from East Kalimantan of Indonesia with a total sulfur and ash content of 2.56 and 7.21%, respectively. The indigenous bacteria used in this,Removal of Sulfur and Ash from Coal Using Molten,The best removal of ash was observed by using 1 M bortrifluorid (BF3) solution at 250°C and 70 atm. Depending on the leaching conditions and coal used, reductions ranged from 5% to 36% in sulfur,US4270926A - Process for removal of sulfur and ash from,,A process for reducing the sulfur and ash content of coal wherein coal particles are treated in an aqueous slurry with a minor amount of hydrocarbon oil to form coal-oil aggregates. The coal-oil aggregates are separated from ash and mineral matter in the slurry by dissolved gas flotation. Optionally, the coal particles may be treated with a conditioning agent prior to the aggregation step.Application of Froth Flotation Technique to Reduce Sulfur,,settle ash contents from coal and a better option for the removal of sulfur from the sample. In the second series of the experiments, different particle size of coal (63um, 125um, 180um and 250um) were selected and their impact on the removal of ash was observed using diesel as a frothing agent as shown in Table III. The results show that the,
