Background: Kaolin is a clay mineral with Al2Si2O5(OH)4 structure which can be found in sedimentary rocks also known as clay stones. Kaolin consists of clay materials such as quartz, illite, smectite, and hematite, with the largest constituent component being kaolinite. Kaolin is one of the most common minerals with an abundant presence in the
