Abstract:

Representative coal samples from the eastern salt range (Modern Engineering and Kishor coal mines, Pakistan) and the central salt range (Punjmin coal mine, Pakistan) were collected and examined for their chemical composition. The chemical characteristics indicate that the salt range coal belongs to sub-bituminous category. Washability analysis on selected coal samples (6.70 ´ 0.212 mm) using zinc chloride solution with a specific gravity from 1.3 to 1.7 were executed. The results classify the central salt range coal as easily washable while, the Eastern salt range coal as moderately difficult to wash. Jigging, shaking table and spiral techniques were applied to check the cleaning amenability of the salt range coal through these techniques. Among these techniques, shaking table revealed the most promising results for all the three coals. Punjmin coal showed the maximum rejection of ash of 55% and that of total sulphur of 74% with a recovery of 46%.
