Research Progress on Resource Utilization of Fly Ash Acid Leaching Residue after Aluminum Extraction
Year: 2025
Type: article
Abstract: In the process of extracting alumina from fly ash by acid method, the acid leaching residue is the main solid waste. The main component of acid leaching residue is silicon dioxide, which can be used as a high-quality silicon source for many silicon-based materials. Using acid leaching residue as raw materials, white carbon black, molecular sieves, mesoporous materials, ceramic materials, rubber fillers and other products can be prepared. The research progress on resource utilization of acid leaching residues is reviewed, its future development is prospected, and the development direction towards high added value, low cost and green environmental protection is proposed.
