The aim of this paper was to identify processes forming the largest amounts of dust and to develop and test additional methods for suppressing dust emissions into the air of the working area for the main occupations, primarily at the stage of loading ore raw materials into the ore-smelting furnace for the silicon production. Using the method for determining the specific surface area of fine materials - the Brunauer-Emmett-Teller (BET) method - it was shown that gas cleaning dust of the silicon production has a developed surface and high wetting ability, which makes it possible to recommend dust suppression methods using irrigation systems. In assessing occupational risks, it has been found that the level of risk is high, working conditions are hazardous and it is necessary to take measures to reduce the dust content in the workplace through the introduction of effective dust suppression systems.
