    • A method of disposal and utilisation of dusts from the combustion installation and sludge from flotation enrichment of non-ferrous metal ores containing hazardous substances, in the process of light aggregate production for the construction industry, wherein the dusts from the combustion installation and/or the sludge from flotation enrichment of non-ferrous metal ores with the fraction of 0 to 0.2 mm are mixed with silica dust with the fraction from 0 to 0.063 mm, and then the resulting product is mixed with particulate glass waste in the form of dust with the fraction of 0 to 0.2 mm and waste sludge from wastewater treatment plants with a content of 15 to 50% of combustible components and/or sludge from coal flotation containing up 32%) of coal, and the resulting mixture in the form of a thick paste is granulated to form granules with a fraction from 2 to 20 mm, which after drying are subsequently converted thermally in a temperature from 1000 to 1200°C, till the moment of incorporation of the hazardous substances into the polycrystalline structure of the sinter with the properties of a lightweight aggregate. Waste in the form of fine dusts from the combustion installation and/or sludge from flotation enrichment of non-ferrous metal ores, silica dust and glass dust are premixed, and then waste sludge and/or sludge from coal flotation is added, and the entire mixture is stirred till a homogeneous mixture for forming granulate is obtained. Hazardous substances from hazardous waste are stabilised as a result of a thermal synthesis in the produced lightweight aggregate in the form of solid silicate compounds. The combustible ingredients of waste sludge and/or sludge from coal flotation are burned out at the stage of sintering, generating gases which cause the formation of pores in the granules.
