Abstract
This work tested whether using viscous glycerol solutions to restore the laminar flow condition could improve the separation performance of the laboratory Reflux Classifier for larger particles. For 0.25-2.0Â mm coal particles, using 50Â wt.% glycerol solution in 6Â mm channels, the Reflux Classifier was able to match the float-sink yield-ash curve across the entire yield range. For 2.0-16Â mm coal, using 70Â wt.% glycerol solution in 24Â mm channels, the Reflux Classifier gave results which were at worst only 1.0Â wt.% ash units off the float-sink curve. Hence the Reflux Classifier can potentially replace the float-sink method for measuring the washability of small bore core samples and producing clean coal composites.
