The purpose of this study is to develop a washability analysis system for fine and ultrafine coal particles using Density Gradient Centrifugation (DGC) and Thermal Gravimetric Analysis (TGA) techniques. The unique advantages of this proposed technique is that it provides a means to obtain usable washability curves on fine and ultrafine coal samples. The DGC technique will produce a large number of density fractions in a single run and, thus, is much faster and more efficient than normal washability analysis. During this quarter all of the samples to be used in this study have been received and reduced to the required size ranges. The set of 48 samples of IBCSP 101 have been separated by the DGC technique and submitted for moisture, ash and sulfur analysis.
