Flotation of Low Volatile Coking Coal Fines

Low volatile coking (LVC) coal reserves have become the key for sustaining the coking coal production in India. Because of high ash content and difficult washability characteristics coking coal in India is usually cleaned at 16–18% ash content. To obtain a reasonable yield at this ash level, LVC coal needs to be crushed to less than at least 13 …

Release analysis of coal fines: Evolution of the methodology …

An ideal procedure to determine the limits of flotation-based separation, as is the case with washability analysis for density separation, does not exist. Therefore, a procedure called release analysis, considered to be the counterpart of the washability process in density separation, was developed to evaluate the flotation characteristics of coal fines. Since …

The use of release analysis to show the selectivity of …

ABSTRACT Release analysis is used to characterize the cleaning ability of coal fines. It defines the limit of separation at any target level of ash. Since flotation depends upon many factors like feed size and its composition, surface properties, and type of reagents, it is important to characterize the optimum boundary of separation. Release …

Frother performance was also found to vary with the same size of the two coals. The performance of the synthetic frother and MIBC was found to be superior for the − 0.5 + 0.1 mm and − 0.1 mm feeds, respectively. MIBC performed best for the − 0.5 mm feed of one coal, whereas the synthetic frother did the same for the other coal.
