Coal is a highly variable substance with an exceedingly complex chemical structure, which has not yet been fully and conclusively defined. The relative hydrophobicity of the surface of a coal particle varies according to its innate chemical composition and can be altered by oxidation due to air exposure. Relative to petroleum, coal may be more hydrophilic; relative to water it is clearly hydrophobic and not readily wetted by water. This is particularly true for freshly ground coal which has surfaces which have not been altered by air oxidation. In the absence of surfactants, coal particles do not easily disperse in water and tend to form agglomerates or clumps of particles. 展开
