The efficiency of the flotation of the fine unburned carbon from coal fly ash (CFA) is closely dependent on the dispersion of the collector on the carbon surface. In this work, we carried out the froth flotation tests of CFA using four different surfactants: Sodium Dodecyl Sulfate (SDS), Sodium Dodecyl Benzene Sulfonate (SDBS), Tween-80 (TW) and Triton X-100 (TX), to investigate the effect of surfactants...
The complex dielectric constant (permittivity) of water-in-bitumen emulsion was measured for emulsions with water volume fractions ranging from 0 to 0.5, in steps of 0.1. Significant departure from theoretical calculation was observed, and was attributed to the presence of polar components in the bitumen. Owing to the presence of salt in the water phase, the interfacial relaxation was found to be...
