The leaching process appears to be a potentially efficient technology for removing iron impurities from kaolin. After the tests of chemical leaching, the results were considered satisfactory because the kaolin had their brightness values increased between 23% and 32%.
Technique for efficiently removing iron from kaolin.The invention relates to a technique for efficiently removing iron from kaolin by magnetic separation, which is characterized by …
The kaolin coagulation or flocculation method mainly removes iron and titanium impurities in kaolin. The pulp concentration must be lower than 20%, so a large amount of water needs to be released in the subsequent process.
The kaolin purification process mainly includes gravity separation, scrubbing iron removal, and magnetic separation processes to purify and remove impurities from kaolin. However, …
Kaolin condensation / flocculation to remove iron and whitening. At pH 8-11, alkaline metal ions such as Ca 2+ and Mg 2+ were added to kaolin slurry to selectively condense iron and titanium impurities, and then use weak anionic …
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.
Almost all raw kaolin ores contain 0.5%-3% iron minerals, such as magnetite, hematite, ilmenite, pyrite, rutile, etc. It is to use the magnetic difference between kaolin and gangue minerals to remove these colored impurities. Learn more about Magnetic Separation Plant. For strong magnetic minerals(magnetite, ilmenite, etc…

There are basically two ways for removing titanium impurities by selective flocculation: i) disperse kaolin in a water suspension, flocculate the TiO2 impurities and separate them by sedimentation; ii) disperse kaolin in a water suspension, flocculate the kaolinite, keep impurities in suspension and separate them by sedimentation.
The kaolin purification process mainly includes gravity separation, scrubbing iron removal, and magnetic separation processes to purify and remove impurities from kaolin. However, chemical treatment and flocculation methods are sometimes needed to process kaolin further.
Iron oxide existence in kaolin is biologically induced, so it is better to apply a biological process for removing it from clays by exploiting microorganisms (Poorni and Natarajan, 2013). Interaction of microbes with clay minerals conserves the clay structure, fertility, and chemistry of the soil through the cation exchange and pH buffering ...
Technique for efficiently removing iron from kaolin.The invention relates to a technique for efficiently removing iron from kaolin by magnetic separation, which is characterized by comprising the following steps: (1) purifying kaolin raw ore to obtain a magnetic separation raw material; (2) adding water to the magnetic separation raw material ...
