Abstract
Disclosed are methods of processing kaolin to produce two distinct grades of kaolin in a simultaneous manner. The methods involve processing kaolin by degritting a kaolin crude; subjecting the degritted kaolin crude to flotation to provide a kaolin having reduced titania content; ozonating the kaolin having reduced titania content; centrifuging the kaolin to provide a coarse stream and fine stream; refining the coarse stream into a coarse engineered kaolin pigment; and refining the fine stream into a fine glossing kaolin pigment. Also disclosed are systems for the automated processing of kaolin to produce two distinct grades of kaolin with real time feedback.
