Coal washability analysis by x-ray computed tomography

Abstract X-ray computed tomography (CT) has been shown to be an excellent tool for the study of internal structure and multiphase texture of solids in a noninvasive, nondestructive manner. Now with new reconstruction algorithms and advanced computer systems, quantitative CT analysis is possible. In this regard, a step-by-step procedure for the determination of coal particle density by X-ray CT has been developed. Using appropriate algorithms, the feasibility of the construction of coal washability curves by quantitative X-ray CT analysis has been demonstrated
