Magnetic Separation of Kaolin Clay Almost all raw kaolin ores contain 0.5%-3% iron minerals, such as magnetite, hematite, ilmenite, pyrite, rutile, etc. What is Magnetic Separation? It is to use the magnetic difference between kaolin and gangue minerals to remove these colored impurities. Learn more about Magnetic Separation Plant.

As a result of magnetic treatment, an utterly unusable kaolin was converted to filler brightness. Subsequent chemical leaching of this whole fraction clay resulted in an 89 brightness which would put this clay in the premium brightness range. Magnetic separation in kaolin processing is a comparatively low cost and versatile technique.
Abstract In the present study, changes of iron content, brightness, particle size, mineralogy and paramagnetic properties of kaolins before and after superconducting high gradient magnetic separation (SHGMS) were investigated. The Fe2O3 contents of the feed decreased by 56% after 3.5T SHGMS with 1# steel wool, but higher magnetic intensity to 5.5T did not …
The magnetic eld intensity (I) has a less important inuence while the grain size has an average inuence (positive on the iron recovery but a negative one on the recovery of manganese).
