The wet process includes three stages of ore preparation, beneficiation processing and product processing. The preparation phase includes operations such as batching, crushing and sizing. The mash is to mix the kaolin ore with water and dispersant in the pulverizer. The mashing operation can disperse the.
Production advantages are that the process uses conventional equipment and ordinary flotation reagents. Minerals such as calcite, fluorspar, silica, barite, sulphur, etc., are possible carriers.
The first step in processing kaolin clay is to slurry it in a blunger with water and a dispersing agent. Degritting using screens, cyclones and hydro-classifiers is the next step. The minus 325 mesh degritted clay is fractionated using centrifugal sizers to produce the fine fractions demanded by the various markets. Bleaching, filtering, and drying complete the general processing steps.
The flowsheet in this study follows the general steps outlined above but Ultraflotation is included to produce a high brightness product from the fine fraction. Bleaching alone will not produce the desired brightness.
The froth products from the reflotation and scavenging steps are combined and impounded. The principal contaminant removed in the Ultraflotation process is a titaniferous mineral which does not bleach and imparts a yellowish-brown cast to the finished kaolin if present. Typical results of the Ultra-flotation separation are shown in the table.
In brief, the thickened kaolin from the thickener is bleached, filtered, dispersed and dried. The Ultra White 90 product is then shipped in bulk or bags or as a 70 slurry in tank cars.
The Fe2O3 content, which affects the brightness of the clays is controlled by careful mining and by the reducing bleach using zinc hydrosulphite. The ferric iron is reduced to the ferrous state and the slip washed to remove soluble salts.
In general, Ultraflotation enhances the brightness of the kaolin by more than 5. By incorporating bleaching for additional color improvement, the beneficiated product Ultra White 90 has a brightness of 90-92. Brightness is a measurement of light reflectance by a standard method of the Technical Association of the Pulp and Paper Industry.

When the dry method requires high whiteness of the product, the product produced by Raymond mill must be dry-removed. The dry process has the advantages of eliminating the dehydration and dry process of the product, reducing the loss of the ash powder, short process flow and low production cost, and is suitable for drought and water shortage areas. However, it is necessary to rely on the wet process to obtain high-purity high-quality kaolin.
