Abstract: All types of coal can be oxidized, especially lignite and the oxidation process enriches the coal with humic acids. If oxidized lignite is then treated with a base solution (KOH, NaOH), humates are formed, products similar to humus, which can be used in production of organo-mineral fertilizers. Lignite, which is used in the experiment was excavated from the roof mine layers and fragmented to the granulation size of 0-15 mm and pre-dried in an oven at 105 °C. Using the process of neutralization of oxidized lignite using KOH, under different neutralization conditions, potassium nitro humate was synthesized, which was confirmed by the FTIR method. In all samples of potassium nitro humate the content of humic acids, K2O and total nitrogen were determined. Based on the obtained results the optimal synthesis conditions were determined depending on the concentration of KOH, the volume of the KOH solution used, as well as the duration of oxidized lignite neutralization.
