The paper presents the results of measurements of concentrations of dust substances in flue gases from the mixing process of two type od raw materials (HCC and Rubba) used in the manufacture of fine carbon and graphite products. These raw materials differed in the method of preparation including the heating temperature in various stages of mixing and duration of the process. Due to the use in the mixing process liquid binders, significant amounts of tar substances in liquid and solid phase were discharged from the mixers. In the analyzed flue gases was determined total dust content of tar substances, polycyclic aromatic hydrocarbons (PAHs) and total organic carbon in the solid phase.
