[0002] Fly ash is the main solid waste discharged from coal-fired power plants. If a large amount of fly ash is not treated, it will produce dust and pollute the atmosphere. If it is discharged into the water system, it will cause river siltation, and the toxic chemicals in it will also cause harm to humans and organisms. The main product after coal combustion is fly ash. In fly ash, the main components are aluminum oxide and silicon dioxide, and also include a variety of other components such as ferric oxide, titanium oxide, calcium oxide, sodium oxide and potassium oxide. Metallic aluminum has a wide range of applications in industry. It is necessary to reduce fly ash to obtain metallic aluminum.
