Research Progress on Extraction of Valuable Elements from Fly Ash via Calcination Activation—Leaching Technology
摘要
Abstract
Fly ash,as a large-scale industrial solid waste rich in valuable elements,is a hot topic in the non-ferrous metallurgy industry for recovering aluminum and other elements.Its utilization promotes a more rational allocation of resources and is crucial for improving the overall environmental situation.Firstly,the composition and physical and chemical properties of fly ash are analyzed.Then,the principle of recovering valuable elements from fly ash through roasting activation is expounded.Subsequently,the research progress of extracting aluminum,iron,lithium,gallium,vanadium and other elements from fly ash using the roasting activation—leaching method is systematically summarized.Finally,it is proposed that in the future,the roasting activation process parameters should be further optimized,and green and efficient subsequent separation technologies should be developed to promote the efficient,high-value and sustainable utilization of fly ash.关键词
