On the origin of the name kaolin and the kaolin deposits

 · The Dazhou deposit is an example of a residual kaolin derived from the alteration of granitic rock. The analyses and discussions presented in this paper are essentially based on the field observations and laboratory studies of the Dazhou kaolin. The tailing sand contains essentially of quartz grains and subordinate flakes of white mica. It

Geochemical and mineralogical characterization of the

Kaolinite was the predominant mineral followed by quartz with traces of illite-muscovite Fe-bearing minerals (hematite) anatase and feldspar. The average chemical composition of the kaolin samples was 58.02 wt. SiO 2 28.00 Al 2 O 3 1.48 Fe 2 O 3 1.26 TiO 2 and 0.41 K 2 O (ignited basis).

Capacity assessment of CO2 storage in deep saline

 · Sequestrating CO 2 in deep saline aquifers is maybe the most effective option to mitigate CO 2 emission. The storage capacity of CO 2 is the key factor for site selection before a project is carried out. Most of the existing methods are for assessment of CO 2 sequestered by stratigraphic and structural trapping as well as residual trapping and solubility trapping.
