Abstract
An improved process for producing a aggregated composite pigment having desired physical and optical characteristics when used as a coating, filler or pigment in paper. The aggregated pigment is produced by contacting a substantially dry fine particle size mixture of kaolin and one or more additional feed minerals with a previously hydrolyzed organic silicon compound, such as hydrolyzed tetraethoxysilane, and then recovering the aggregated composite pigment.
