The unburnt carbon recovered from coal fly ash can act as a fuel. The wet flotation process is used to restore coke fines (Niewiadomski et al., 1999; Yao et al., 2015). Froth flotation process can also be used for separating the carbonrich compound from lowcarbon fly ashs and hence lowcarbon fly ashs have played the role of pozzolanic ...
