The material investigated in the course of this study represents a residue from the washing process of a kaolin-bearing Jurassic silica sand, which is dewatered after the separation. The produced filter cake is partly used as supplementary clay for the production of clay bricks but its application is limited.

In this investigation, the possibility of physical separation methods such as attrition scrubbing, hydro-cycloning and also reverse flotation were investigated for silica and calcite removal...

The preparation process of hydrophobic silica aerogel with kaolin as the raw material and dried at ambient pressure is summarized in Fig. 3. The process can be divided into three major steps, including pre-treatment of kaolin, synthesis of wet silica gel, and surface modification and drying of the aerogel.

To remove Fe 2 O 3 impurity, reductive. Conclusions. This study pioneers the production of multifunctional kaolin fillers through delamination and colloidal oxide treatment utilizing nano-scale alumina, silica, and titania. Kaolin particle size was tailored through delamination using dense alumina and zirconia milling media.
