| The physical and chemical properties of Bihar bentonite in comparison to
those of a widely used and well known bent9nite, Wyoming hav1e been studied.
Mineralogically the clay was montmorillonitic with some kaolinite. Gypsum, rutile
and iron minerals were found to be present in the clay as impurities. The clay was
predominantly a calcium-magnesium base bentonite. Due to c9ntamination with
gypsum and to the presence of Ca and Mg as exchangeable cations, Bihar bent,onite
showed very poor physical properties related to its utilisation in ceramic industries.
Preliminary experiments showed that considerable improvement is likely to be
effected by suitable treatments. |
