Research Activities
The department over the years has carried out research in all the aspects of coal preparation. The major thrust was on development of fundamental understanding of processes such as heavy medium cyclones, froth flotation, oil agglomeration, flocculation, etc and their quantification and applicability studies. The research interest includes basic, applied and quantitative studies on water-only cyclones, Vorsyl-separator and comparison of their performance. Theoretical studies on coal crushing, performance analysis of coal crushing circuits, beneficiation of, LVMC coals, non-coking coals, and new flotation reagents development have been undertaken and are in progress. Carbonization of coal with inferior quality coals and additives along with studies on coal oil and coal-water mixtures for combustion of coal formed the initial research activities in Fuel Technology. Presently, spontaneous combustion, beneficiation of thermal coals to improve combustion and flowability are in progress. Current research interest in this area includes chlorination studies, Pelletisation, direct reduction of iron ores, direct leaching of complex sulphide ores and beneficiation and utilization of low-grade iron ores etc. Hybrid Pelletized Sinter, Underground Coal gasification.
