Method for rendering harmless and utilization of dusts from burning installations and pulp from floatation enrichment of non-ferrous metal ores, containing dangerous substances, in the process of production of lightweight aggregate for building industry

摘要

The method of disposal and disposal of dust from incineration plants and mills from the flotation enrichment of non-ferrous metal ores containing dangerous substances, in the process of light crumb production for construction, is characterised by the fact that dust from the incineration plant and/or sludge from the flotation enrichment of non-ferrous metal ores o fraction from 0 to 0,2 mm is mixed with silicon dust from 0 to 0063 mm,and the resulting product is then mixed with the crushed glass waste in the form of a fraction of 0 to 0,2 mm and with the effluent settlements with the effluent treatment plants of 15 to 50% of the combustion constituents and/or sludges after floating of carbon to 32%of carbon, and the mixture obtained in the form of dense paste is granulated into granules of a fraction of 2 to 20 mm which, after drying, are heat-transformed at temperatures from 1000 to 1200'c until dangerous substances are incorporated into a polycrystalline structure of a light-crumbling furnace.
