Abstract

The study aimed the mineralogical and technological characterization of various types of kaolin in the region of Silvânia - Goiás, as well as its physical and chemical processing to eliminate mineralogical impurities and upgrade the level of whiteness of kaolin. 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 Silvânia can be used as filler in the paper industry or in the production of ceramics.
