A Theoretical Approach to Coal Flotation Washability Correlation

This research paper presents a theoretical derivation for analyzing and extracting the coal floatability information. The relationship between combustible recovery and ash recovery was derived. The basic assumptions and the theoretical approach based on statistical distributions are discussed. In addition, the significance of various parameters to describe the floatability, cleanability, and performance of a separation device have also been discussed. Potential uses of this approach have been suggested.
