Abstract:
High-carbon fly ash is a kind of solid waste that can not be used directly. In order to reduce the loss on ignition
of high-carbon fly ash, the decarbonization test of high-carbon fly ash was carried out. Through grinding test, the best
grinding time of high-carbon fly ash is 1. 25 min. Through the flotation reagent system test, it is determined that the best
reagent system is the dosage of Sec-octyl alcohol 4 kg ／ t and kerosene 12 kg ／ t. Through the flotation process test, it is
determined that the best flotat
