Selective flocculation enables the production of high-brightness kaolin products from kaolin ore once considered too poor in quality for beneficiation into paper-coating pigments. Anatase, Ti(1−X)FeXO2, with X = 0 to 0.05, is a common iron-bearing impurity in sedimentary kaolin that can be unresponsive to kaolin beneficiation processes, such as magnetic separation, due to its extremely fine

A single beneficiation process generally cannot meet the production requirements, and multiple combined processes are often used in actual production. It is recommended that all mineral processing plants conduct beneficiation tests first, and determine the appropriate beneficiation plan based on the test data, so as to ensure the grade and recovery rate of the concentrate.

The Super-Fine Crusher shortens the process by removing the need for water and media. Crushing minerals from 10mm down to 10 microns eliminates the need for reprocessing. The Cyclomag utilises the benefits of the Super Fine Crusher to liberate and separate magnetic iron ores during beneficiation. This results in a power reduction of about 20-40% and limits water use to dust suppression and
