Release Analysis by Combining Different Reagents and Choosing Best Reagent in Batch Type Froth Flotation Process for Central Coalfields Limited (CCL) Karma Coal
Froth flotation is a widely used technique for the beneficiation of fine coals, specifically those whose size less than 0.5 mm. In this study, the flotation performance of Karma coal samples from Central Coalfields Limited (CCL) was analysed using the release analysis technique. The experimental samples had a size range of − 0.15 to + 0.074 mm. Various operational parameters such as collector dosage (kg/tonne), frother dosage (kg/tonne), and pulp density (%) were modified to assess their impact on flotation performance. Release curves were plotted to determine the cumulative product percentage and the product ash percentage for different operating parameters. The highest yield achieved was 92.33% with a combination of diesel oil and pine oil at dosages of 0.75 kg/tonne and 0.5 kg/tonne, respectively. This yield had an ash level of 30.65% at a pulp density of 15%. Conversely, the lowest yield of 53.26% was obtained using a single MIBC frother at a dosage of 0.15 kg/tonne.
