Abstract

The paper studies the effect of mechanochemical activation on the elemental composition of shungite rocks of the Koksu deposit. The use of nanostructured shungite powder in sorbents can lead to an improvement in their sorption properties. As a result of mechanochemical activation in samples of shungite rocks of carbonate and shale origin, the mass fraction of carbon decreases, and the mass fraction of silicon increases. The composition of the rocks also increases the content of oxygen, aluminum and iron, which improves the sorption properties of shungite. A decrease in the speed of rotation of the balls leads to a slight change in the content of elements, a decrease in the content of carbon, oxygen and sodium is observed, and the content of silicon, aluminum, iron and potassium increases. An increase in the ratio of the sample mass to the ball mass from 1:1 to 1:3 at a grinding
