Kaolin Ore

Oct 09, 2021 · 3. Selective flocculation. In the selective flocculation process of kaolin, flocculants are added to make the kaolin particles flocculate and sink to the bottom. The irontitanium impurities are reddishbrown in the upper suspension due to the fine particles, and most of the irontitanium impurities can be removed by removing the upper suspension.
