Method for treating electrolytic aluminum ash in cement clinker production
The invention relates to the field of waste treatment, in particular to a method for treating electrolytic aluminum ash in cement clinker production, a rare earth ion doped aluminum ash separating agent is prepared, and the separating agent can increase the tension of the surface of aluminum melt particles and an aluminum ash interface, increase the aluminum recovery rate and improve the quality of recovered aluminum metal; the optimal temperature for aluminum ash recovery is disclosed, molten aluminum is easily polymerized in molten salt within the temperature range, the size of formed aluminum beads is large, and lost aluminum is reduced; according to the invention, the abandoned ash is associated with cement production, and the abandoned ash is prepared into the aluminum silicate cement ingredient, so that the method is a research on abandoned ash resource utilization, finds a new application for application of aluminum ash, and realizes harmless and resourceful treatment of the abandoned ash.
本发明涉及废物处理领域，本发明的一种水泥熟料生产中处置电解铝铝灰的方法，本发明制备得到稀土离子掺杂铝灰分离剂，这种分离剂能增加铝熔体颗粒的表面与铝灰界面的张力，提高铝的回收率，提升回收铝金属的品质；本发明的公布了铝灰回收的最佳温度，在该温度范围下铝熔液在熔盐中较容易聚合，形成的铝珠的尺寸大，损失的铝减少；本发明将弃灰与水泥生产联系起来，将弃灰制备成为硅酸铝水泥配料，是弃灰资源化利用的研究，为铝灰的应用找到了的新用途，实现弃灰的无害化和资源化处理。
