Density cleaning for some Turkish lignites

In the scope of this study, in order to determine the floatability characteristics of lignites, 5 samples were collected from various lignite reserves of Turkey namely Dursunbey, Çayırhan, Ilgın, Ermenek, and Gürmin-Merzifon. Collected samples were analyzed in terms of float and sink analysis. As regards to float and sink analysis, the original samples were floated and sinked in 2 different ZnCl2 solutions of densities 1.40 and 1.60 g cm-3. Proximate analysis of each original sample for the corresponding lignite was carried out in the beginning of this study. In terms of proximate analysis performed, Dursunbey lignite sample has the lowest ash content of 24.86 % while Gürmin Merzifon lignite sample has the highest ash content of 45.02 %, respectively. Accordingly, 5 float and sink analysis graphic obtained and they would help one to understand and easily figure out the optimum medium density for cleaning.
