Cleaning of Dukki (Baluchistan) coal by oil agglomeration process
Cleaning of coal fines by oil agglomeration is an efficient technique by which an appreciable recovery of combustible matter and significant reduction in ash forming minerals are possible. In this study, oil agglomeration process has been employed to clean indigenous coal under the influence of parameters such as oil type, particle size and the pH value of aqueous medium. As agglomerant, castor ...

Experimental studies on hydrophobic flocculation of coal fines in aqueous solutions and flotation of flocculated coal
Hydrophobic flocculation of fine bituminous coal particles in aqueous solutions under mechanical conditioning and without any surfactants has been experimentally studied through the measurements of aggregative efficiency, zeta potential and contact angle in this work. The results have shown that the hydrophobic coal fines strongly aggregated in a wide pH range (3.5?9.5), even though the particle ...
