Synthesis of zeolites from low-cost feeds and its sustainable
Iron ore tailings. Iron ore tailings, a by-product of the ore smelting process, are considered to be a good potential source of silica for zeolite preparation due to their high silica content [44]. Thus, lots of research has been conducted on the conversion of the iron ore tailings to zeolite materials including zeolite A [45] and ZSM-5 [46], [47].Web

Currently, it is difficult to realize environmentally friendly synthesis of zeolites due to the use of the solvent. Therefore, it is of great importance to realize zeolite synthesis from iron ore tailings (IOTs) by a solvent-free method. In this work, in situ formed zeolite crystals are self-assembled and IOTs are converted into hierarchically porous ZSM-5. …Web
