【Abstract】 Research has been made on microstructure of fine coal ash slag by using transmission electron microscope, in which, a new consideration has been put forward, that is improving fine coal ash slag activity by means of reduction of residual carbon in fine coal ash slag. Three processes such as tribo-electrostatic separation, fluidized bed separation and conventional flotation separation and conventional flotation separation are used for that. The quantization analysis has been made on the carbon reduction performance of the three methods. The study indicates these de-carbon methods can be significantly used for reference in dealing with the problems found in comprehensive utilization of fine coal ash slag.更多还原
