ABSTRACT
Fine coke particles were separated from fly ash in a laboratory flotation cell. Almost 90% of particles by number were below 10 μm and one third of them was less than 2 μm. Fly ash was sampled directly from a surge bin in a power plant and from a refuse dump area. Kerosene and Diesel oil were compared as collectors, and MIBC and polyglycol – based agents – were used as frothers. The best separation coefficient of 0.8 was obtained for 18 kg/t of Diesel oil and 9 kg/t of commercial frother based on polyglycol.
