Dewatering of ultra fine coal and tailings slurries using the conventional technologies are difficult. In this report, a novel Centribaric technique was applied to study the effect of surfactants, flocculant, and mixed surfactant flocculant on the dewatering of coal and tailings. The results of both coal and tailings revealed that anionic surfactants were effective at reducing moisture content, but they decreased solid recovery. On the other hand, the effect of the anionic surfactant was negligible ...

This study focuses on the physical aspects of ultrasonic de-ashing and de-sulfurization, such as cavitation, streaming and their combined effects. Ambedkar Balraj proposes an ultrasound-assisted coal particle breakage mechanism and explores aqueous and solvent-based ultrasonic techniques for de-ashing and de-sulfurization. Ambedkar designs a Taguchi L-27 fractional-factorial matrix to assess the individual effects of key process variables. In this volume he also describes process optimization and scale-up strategies. The author provides a mechanism-based model for ultrasonic ...
