The influence of the dry (in the air, without water) and wet (in water) method of brown coal grinding on the extraction efficiency and structural group composition of the extracted humic acids (HA) was studied. The samples of liquid and powder humic preparations (HP) from brown coal of the Tisulskoye deposit (Kaychakskiy site) were produced. The samples were obtained using the original set-up, which allowed us to achieve the high yield of HA using ultrafine grinding of the raw material in the dry form or in the aqueous solution of an alkali. The technical characteristics and regimes of equipment operation are presented. All the samples were characterized by means of technical and elemental analysis, 13C NMR (CPMAS) and FTIR spectroscopy. Granulometric composition and specific surface area of coal samples after dry and wet grinding were determined. It was established that the wet method allows achieving more complete extraction of HA from brown coal due to an increase in the surface area of the contact between coal and the alkali. Both methods of grinding do not have a significant effect on the structural group composition of extracted HA and their biological activity.
