froth floatation in desulfurization

The froth flotation is not efficient in desulfurization because of the low rate of sulfide liberation from raw coal, the natural hydrophobicity caused by sulfur concentration on the surface of sulfide, and the presence of large amounts of middling feed.

This book was written to provide a comprehensive survey of the current state of the art in coal preparation, with particular emphasis on coal desulfurization. Such a book has not been available since Robert Meyers wrote Coal Desulfurization in 1977, and considerable advances have been made in the more than 20 years since then.
