The four specific gravity solutions were prepared for carrying out the wash ability studies of Degari Coal of Balochistan by ZnCl2 which are as followed 1.25, 1.3, 1.35, 1.4 respectively. The wash ability studies of Degari Coal have been completed. The results showed that the Calorific Value of Degari Coal have been upgraded to 13565 btu/lb which was earlier 9875 btu/lb and the ash content is reduced from 50% down to 30% with an increase in Fixed Carbon up to 4%. The maximum recovery of 90% was obtained during the float sink of-3/4 " +1/2 " on 1.40 specific gravity solution. The results which were obtained 2.39, 5.62, 48.15, 46.25, 13565 and 3.36 were moisture, ash, volatile matter, fixed carbon, Calorific value and Sulphur respectively. The weight recovery on the specific gravity solution is 90% with the maximum calorific value of 13565 btu/lb.
