Correlation of mineral composition of the parent rock with the mineral composition of kaolin
Commercial kaolin deposits are only formed from acid rock. In the weathering processes quartz grains of primary rock are conserved without any changes of size. Large kaolinite flakes arise in the place of mica by epitaxial growth on a mica sheet. Some part of iron and titanium is preserved in specia...

Tartalmi kivonat: | Commercial kaolin deposits are only formed from acid rock. In the weathering processes quartz grains of primary rock are conserved without any changes of size. Large kaolinite flakes arise in the place of mica by epitaxial growth on a mica sheet. Some part of iron and titanium is preserved in special minerals formed within pseudomorphs after biotite. K-feldspar changes into small newly formed kaolinite flakes. On acid plagioclase halloysite appears but on andesine-labrador montmorillonite arises. Properties of commercial kaolin depend upon all the peculiarities of the mineral transformations. |
