Biological beneficiation of kaolin: A review on iron removal
High quality kaolins are also low in iron-bearing minerals. The existence of iron oxides in kaolin adversely affects the clay color, and reduces its brightness and refractoriness (Ryu et al., 1995, de Mesquita et al., 1996, Lee et al., 2002, Mockovčiaková et al., 2008). These cause a dramatic decrease in its commercial price (Guo et al., 2010).
