Résumé
For decades, the world has experienced a steadily increasing demand in the extraction of a variety of different minerals from the earth's crust through mining processes. This has resulted in two major consequences: i) depletion of limited mineral resources of the earth, and ii) generation of large amounts of residual products in the mining and metallurgical sectors, that are disposed of in tailing ponds or landfill sites. These issues have caused that the world is encountering with incredibly serious economic and environmental challenges. Reuse, repurposing and valorization of these residues have been determined as effective and sustainable approaches towards struggling with economic and environmental issues related to the exploitation of low-grade deposits. These residues are divided into several categories according to their chemical and mineralogical compositions, since these parameters play essential roles in their repurposing/valorization. Among these residues, aluminosilicate bearing residues have demonstrated promising potential as inexpensive raw resources to produce valuable materials. In the recent years, these residues have been intensively investigated for their use in the production of cost-effective zeolites, which are crucial materials for catalysis and adsorption–separation industries. This alternative in zeolite production is of continuous interest in the field of zeolite science due to: i) important reduction in zeolite production costs, ii) sustainable development concepts as well as iii) helping to tackle the environmental concerns related to long-term management of residues. Herein, the endeavor is to discuss about the state-of-the-art technologies for zeolitization of aluminosilicate bearing residues including coal fly ash, clay minerals residues, Li slag, Al production residues, with an emphasis on the ongoing struggles in improvement of their corresponding zeolitization processes.
