The floatsink test is a commonly used technology for the study of coal washability, which determines optimal separation density for coal washing based on the desired sulfur and ash yield of the cleaned coal. In this study, the floatsink test is adopted for a highsulfur Late Permian coal from Hongfa coalmine (), southwestern Guizhou, China, to investigate its washability, and to analyze ...

naturally occurring deposits in such forms and amounts that economic extraction is currently or potentially feasible (Wood et al., 1983). Coal reserve is a more restrictive term describing the part of the coal resource that can be mined economically, at the present time, given existing environmental, legal, and technological constraints (Wood et al., 1983).
