In this study, Zonguldak, a Turkish city popular with coal mining, was taken into consideration. Coal was the main source of energy for domestic heating in Zonguldak and tonnes of ash were dumped to environment. The ash samples were containing carbon and this carbon was aimed to recycle from these waste. In the order of this recycling, firstly classification of collected ash samples in terms of size groups was carried out. For each size groups sink and float analysis was carried out. Sink and float analysis was carried out with densities (1.30, 1.45, 1.60, 1.90 g/cm 3 ) for a total of 5 size groups of ash (+18.00mm, -18.00+10.00mm, -10.00+6.00mm, - 6.00+2.36mm, -2.36+0.50mm) and each floated product was analysed in terms of final ash percentage. Size group -18+10 mm was floated at 1.30 g/cm 3 and it was observed that this group of coal ash has the highest percentage (%58.84) carbon.
