Accordingly, a pre-agitating technique followed by high-pressure washing of the sample on a 600 μm sieve were applied. In this method, by discarding up to 20% of the raw material, >54% of the total iron content of the raw kaolin was removed, and the iron content was reduced from 9.75% in the initial sample to <6.00% in the passing fraction.
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 …

Iron is one of the most stubborn impurities in quartz minerals, and the iron content partly determines the various applications of quartz. Iron can exist in quartz in the forms of iron minerals, fluid inclusions, and lattice impurities. The removal of iron and the consequent purification of quartz minerals are the key processes to obtaining high …
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. ...

challenge, this study was conducted to assess the effect of wet processing and oxalic acid treatment in the removal of iron oxide bearing impurities from Alkaleri and Onibode kaolin to meet ...
methods reject titanium impurities as part of the overflow fraction and both are capable of removing substantial portions of the original TiO2 content. This ability to separate anatase particles from kaolin establishes that at least a portion of the titanium impurities occur in kaolin as a discrete phase.
