Optimization of Coal Washery Tailings by Flotation Process

Flotation tailings are by-products of coal preparation plants, which do not only occupy cultivated land but also cause pollution. The high ash content and low calorific value of tailings limit their applications. Deashing is the precondition for the reutilization of flotation tailings. However, it is more difficult to remove ash content from flotation tailings The notification which was issued on May 21, 2020, stated that the process of coal washing leads to extensive pollution. “Ash generated during washing pollutes water and cannot be gainfully utilized. The process involves increased water use, effluent generation, fugitive dust and the disposal of washery rejects has negative environmentalCoal washeries function despite Centre notification in May

FLOTATION PERFORMANCE ANALYSIS ON COAL

Coal washery rejected coals and coal slurries have better options in froth flotation as a separation process. In this study, coal slurry received from Sudamdih coal washery, Jharkhand, India, examined for cleaning through fixed cell flotation. The Petrography study of the feed sample showed the presence of vitrinite, semi vitrinite andThe huge quantity of effluent generated in coal washing processes contains large amount of suspended and dissolved solids, clay minerals, coal fines and other impurities associated with raw coal. The present system of recirculation of the effluent is found to be ineffective in removing colloidal fines, which is the major part of the impurities Characterisation of coal washery effluent and optimisation of
