Abstract: Obtained dates of concentrated humic preparations (HP) are presented. HP are produced by the "dry" and "wet" method from the brown coal of the Tisulsky deposit. Samples of HP are characterized by technical and elemental analysis. Granulometric and surface area are determined. The description of the processes proceeding is provided at all stages of receiving HP. The "wet" method allow to achieve fuller extraction of the humic acids (HA) from brown coal by increase surface area of the alkali and coal.

Key words: brown coal humic preparations crushing
