Abstract The article describes the way of metallurgical wastes processing technology of lead production waste slag processing with the subsequent obtaining of lead and zinc by heat treatment. The analysis of existing technologies was carried out and the relevance of industrial wastes processing was revealed, which proved the necessity of this research. Modern instrumental methods were used in the research, confirming the correctness of the experimental work and the results. On the basis of the experiments carried out with metallurgical wastes it become clear, that they contained toxic metals, being a dangerous source of environmental pollution and at the same time a target material. The technology of lead production slag processing by using a drum furnace with subsequent production of non-ferrous metals is recommended. The thermodynamic patterns of the processes occurring during the processing of lead production slag have been studied and thermodynamic parameters have been determined, especially the value of enthalpy, entropy and Gibbs energy in a heterogeneous system. The developed technology makes it possible efficiently to process the industrial waste slag of lead production. The developed technology is also aimed at reducing of the accumulated industrial waste, which in turn makes it possible to regulate the environmental situation in the region.
