Clean Fuel Production from Coal Washery Plant Wastes vith Soybean Oil

In this study, agloflotation experiments were conducted and fine (<500 μm) wastes from a coal washing plant operating in Zonguldak were used. 33.75% ash wastes were mixed with soybean oil and agglomerated, then taken to a flotation cell and clean coal/fuel was floated in this cell. The yield of the floating clean coal was 56.40% by weight and the content of ash was 14.80%. The net calorific value was increased from 3620 to 5072 kcal / kg. In addition, tests were conducted with kerosene, a fossil fuel and widely used in flotation, and the results were compared with those of soybean oil. Soybean oil as a collector showed about 20% lower performance than the kerosene in terms of efficiency and selectivity
