The physicochemical composition of the used waste clay adsorbents was studied to justify the possibility of obtaining other silicate new products, and it was found that they did not differ from the original ones. It was determined that the chemical composition of all samples met the requirements for porous materials. It was determined that bentonites have the highest rate of increase.

One of the most important indicators of mechanical activation of clay minerals is the effect of activation time on the strength of the mixture. One of the most important parameters in the preparation of drilling fluid based on clays is their ability to swell, and the effect on the swelling of clays during mechanical activation was studied. One of the most important parameters of clays used in the preparation of drilling fluids resistant to thermomechanical effects is their colloidal index. Therefore, the effect of mechanical activation time on the colloidal index of these clays was studied. The method of activation of bentonites and analysis of their rheological parameters was studied. In the process of mechanical activation of clays, their activation of chemical reagents created conditions for modifying the increased specific surface area of clay materials.
