An experimental investigation was carried out to develop a flotation technique for the efficient beneficiation of Iowa coal fines that could be applied on a pilot plant scale at the Iowa State University coal preparation plant. Flotation techniques found to be effective on Appalachian coals were studied to determine their effectiveness on Iowa coals. A single-stage flotation technique using metal salts was studied at different pH values. The effects of metal salt concentrations and different frother agents were also examined. Flotation techniques that performed well on Appalachian coals were found to be less effective on Iowa coals. the metal salts tested behaved more as coal activators than as pyrite depressants. The frothers examined exhibited collector-like properties. A single-stage flotation technique using 10 -4M concentration of metal salts and MIBC as the frother was found to effectively beneficiate Iowa coal fines.

This book was written to provide a comprehensive survey of the current state-of-the-art information in coal preparation, with particular emphasis on coal desulfrization. The primary audience for this book will be practising coal preparation engineers who need complete information about all of the coal preparation and desulphurization technologies that are available now, or that may be available in the future. It will also be valuable for coal researchers who need details and comparative data for cutting-edge technologies that are still under development. The main emphasis is on physical coal preparation, but chapters also include chemical and biological technologies that are under development, but not yet used in industrial practice. Along with the successful technologies, also included are details of processes and techniques that were attempted, but were subsequently abandoned, along with discussions of the reasons they were abandoned.
