hard kaolin versus soft kaolin

Chemical composition and surface property of kaolins

Nov 01, 2003· The floatability of hard kaolin was lower than that of soft kaolin. Hard kaolin was the dominant kaolin in bauxite. A new type of collector for hard kaolin was studied in order to selectively separate kaolin from diaspore in bauxite. The surface zeta potential variation of the hard kaolin as a function of pH was almost the same as that of the

Engelhard Minerals & Chem. Corp. v. Anglo-American Clays

A. Hard v. Soft Kaolin. The novelty of the invention described in the patent in suit is clearly premised on the use of hard or gray clay. Hard clay is mentioned over 50 times in the patent, and the unexpected success of this clay as a paper pigment is central to plaintiff's claim of uniqueness. The patent defines hard clay by comparison of its

Chemical composition and surface property of kaolins

The surface zeta potential variation of the hard kaolin as a function of pH was almost the same as that of the soft kaolin. The IEP of the hard kaolin varied from 2.5 to 3.8. The SiO 2 (wt%) content of the several kaolins showed negative correlations with IEP, but Al 2 O

Kaolinite Wikipedia

Kaolinite (/ ˈ k eɪ ə l ɪ n aɪ t /) is a clay mineral, with the chemical composition Al 2 Si 2 O 5 4.It is an important industrial mineral.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 Imerys

Kaolin is formed when the anhydrous aluminum silicates found in feldspathic rocks, like granite, are altered by weathering or hydrothermal processes. The process which converted the hard granite into the soft matrix found in kaolin pits is known as ‘kaolinization’. The quartz and mica of the granite remain relatively unchanged whilst the
