“…Kaolinite (Al 2 Si 2 O 5 (OH) 4 ) is a common clay mineral formed from altered rocks and a source of alumina impurities. , Known for its excellent adsorbent properties, it has been largely studied for the removal of pollutants, such as heavy metals, , dyes, and phenols , from wastewaters, thus constituting a promising material for the environmental domain. Yet, due to its main composing elements (Al and Si), kaolinite is also known for being deleterious to metallurgical processes, reducing both efficiency and productivity, , especially in iron ore recovery.…”
