Abstract: An opacifying kaolin pigment with improved porosity, light scattering ability (opacity), gloss, and ink receptivity over that of the starting pigment is manufactured by a process which comprises the steps of treating an aqueous solution of kaolin with a phosphate compound, using the endogenous aluminum leached from kaolin and/or adding a soluble aluminum compound and increasing the pH of the mixture. The kaolin aggregates are prepared at temperatures between 5 DEG C and 200 DEG C.

Abstract: Described herein are technologies for concentrating rare-earth elements from a heavy fraction of grit in gangue produced in kaolin mining. In some examples, grit is separated as a non-clay fraction of gangue produced in a kaolin mining operation. The grit is separated into a heavy mineral grit sub-fraction and a light mineral grit sub-fraction. Rare-earth elements, particularly heavy rare-earth elements, are thereafter extracted from the heavy mineral grit sub-fraction using various extraction technologies.
