Abstract
This paper summarizes the results of the comparison of the washability characteristics of three coals (anthracite, brown, and lignite) by the VIKOR method. Based on the float-sink test results, the theoretical values of the coal yield and the quality of the clean coal product were calculated. Two washability parameters, the Index of Washability (IW) and the Near Gravity Material Index (NGMI), as well as the Separability Coefficient (K), were computed, and the results were compared. The results presented in this study indicate that the washability of the anthracite coal is relatively easy at a specific density of 1650 kg/m3.
