Kaolin available in Deopani, Assam of northeastern region of India was characterized by FTIR, XRD, DTA and by wet chemical analysis methods. The major impurities in the clay are quartz and siderite. Wet sieving of the clay by −53-μm sieve removes almost all the quartz and a major amount of Fe bearing impurities.
A practical guide for particle size analysis using wet sieving method. Importance of sieving w/wet wash test sieves, various procedures and helpful tips & tricks.
Kaolin is widely used in industry and commerce, and physical Beneficiation methods are very necessary in removing iron impurities from kaolin.
Drying: The wet kaolin concentrate obtained from froth flotation is then dried using various methods, such as spray drying, rotary kiln drying, or flash drying. This helps to remove the remaining moisture from the kaolin and …

The chemical leaching process of the low-quality kaolin (high colouring impurities) gave the following results: The brightness of kaolin improved from 56% to 86%. Removal of 94% of total iron gives a product containing 0.48% Fe 2 O 3, which is suitable for industrial applications.
The removal of impurities from the sieved clay was done by physical separation of the dirt, followed by a wet/soaking method as described by Aroke et al. (2013). 100 g of the powdered bulk clay sample was soaked in a plastic container with 1000 cm 3 of de-ionized water for 48 h. The resultant slurry was plunged and screened …
A Study of Iron Removal from Kine Kaolin by Two Liquid removal of iron impurities from silica by floatation. However in most kaolin deposits there are various impurities which have a very bad effect on the quality of the kaolin Therefore it is necessary to remove these impurities from kaolin ore Owing to their similar surface properties the …

The present study deals with flotation, selective flocculation, leaching and dewatering tests conducted on East Georgia kaolin clay. Flotation and selective flocculation tests were performed on the samples to remove titanium impurities (TiO2) using different reagents at pH 9.5. The leaching tests were applied to the treated samples to dissolve …
However, the beneficiation process reduced the percentage of contaminants with the minor label. Wet physical beneficiation of kaolin was more effective in removing kaolin impurities. Benefaction results indicated significant removal of iron oxide and titanium oxide from raw kaolin.

The removal of impurities and dirt from raw kaolin was accomplished through physical separation, followed by the wet/soaking process according to the …
Quartz and feldspar products require low iron content, so it is necessary to completely remove iron impurities, most of which are weakly magnetic ores. It is found that the high gradient wet magnetic separator with a magnetic induction intensity of 1.5 T (Tesla) is more excellent for strong magnetic separation.

Water soluble impurities can be removed by washing with deionized or distilled water and filtering, and organic solvents may be used for removing water-insoluble impurities. Acid leaching sometimes is employed to remove metal contaminants. Magnetic separation is used to extract magnetic impurities from either dry powders or wet slurries.
The flotation process can effectively remove iron, titanium and carbon impurities in kaolin, and realize the recycling and reuse of low-grade kaolin resources such as coal-measure kaolin. Kaolin clay particles are finer and more difficult to float than gangue minerals.
