Incineration is a modern global trend in the disposal of combustible solid waste. When burning garbage, solid incombustible residues are formed – slags containing aluminum, copper, zinc and lead, in quantities many times higher than the maximum permissible concentrations of these elements in soils. The material composition and morphostructural features of the material were analyzed to determine possible areas of use and ways of utilization of waste incineration plant slags. As a result of microprobe researches forms of finding of ecologically controlled elements in slag are established. Test results of slag concentration by gravitational methods and results of magnetic separation are given. Based on the studies, a basic outline of slag product processing is proposed.
