摘要： The method of making an enhanced pozzolan from fly ash which contains a substantial carbon content includes screening (11) the raw fly ash and using conditioning agents, applying the ash to a first set of flotation tanks (15) for removing a carbon rich fraction and a non-carbon rich fraction, subjecting the carbon rich fraction to attrition milling (20) to fraction the carbon particles and to release microspheres captured within the carbon vesicles, applying the milled carbon rich fraction to a second bank of flotation cells (22) and separating a second carbon rich fraction which contains fractured carbon particles and carbon particles which have been reduced in size and a second non-carbon fraction containing mainly fly ash microspheres, combining the non-carbon fraction containing mainly fly ash microspheres, combining the non-carbon fractions and drying these fractions in a heated screw-type dryer (30) and breaking up any agglomeration of particles providing a reactive fly ash pozzolan which contains a substantial portion of fine particles including microspheres.
