Kaolinite - Wikipedia

Kaolinite (/ ˈ k eɪ ə l ɪ n aɪ t /) is a clay mineral, part of the group of industrial minerals with the stone composition Al 2 Si 2 O 5 4.It is a layered silicate mineral, with one tetrahedral sheet of silica (SiO 4) linked through oxygen atoms to one octahedral sheet of alumina (AlO 6) octahedra. Rocks that are rich in kaolinite are known as kaolin / ˈ k eɪ ə l ɪ n / or china clay.

kaolin ore size [Click to learn more] - pizza-club.be

Kaolin clay is produced from ore having silica sand content in quantities that inhibit air separation of the silica sand from the kaolin clay by subjecting a slurry of the ore to agitation so that the silica sand acts to reduce or smear the kaolin clay to substantially natural particle size.
