Abstract

This study was undertaken to assess the cleaning potential of Dulmial-Punjab coal by froth flotation.
Release analysis was performed to determine the optimum flotation response of the coal. Number of batch
flotation tests were performed to investigate the effects of various parameters such as particle size, impeller
speed, collector dosage, frother dosage and conditioning time on clean coal yield and ash content. It was
found that maximum yield of 51.25% with 39.5% ash content was achieved at impeller speed, collector
dosage, frother dosage and conditioning time of 1600 RPM, 1200 g/t, 200 g/t and 10 min, respectively.
