The kaolin of this region presented kaolin absolute properties, is fine to medium grained, after chemical bleaching, its whiteness reached 68.10% ISO. The results indicated that the kaolin of the region of Silvania can be used as filler in the paper industry or in the production of ceramics. %K Kaolin %K processing %K mineralogical characterization %U http://www.anuario.igeo.ufrj.br/2009_2/2009_2_26_32.pdf
