This study aimed of the effect of the moisture content of the surface layer of tailings on the emissions of solid suspended matter, as well as on the study of the efficiency of dust emission by aqueous dispersions of poloxamer. The dust suppression capacity was assessed by comparing the dust concentrations generated in the dust suppression bunker space as a result of the air flow action on untreated and dust suppressant treated samples. In an experiment on sand samples from the copper-molybdenum ore beneficiation tailings, it was found that a 2% poloxamer solution provides dust suppression efficiency of up to 98% and retains moisture in the samples for at least 14 days. These data are of interest for the creation and implementation of effective methods for managing pollution from tailings of the mining and processing complex and in other industrial sectors.
