The physicochemical regularities of the carbon-thermal reduction of zinc and iron oxides from blast-furnace sludges, as well as from the dusts of gas-cleaning installations of steel-smelting furnaces, have been studied. With the use of kinetic analysis, the optimal parameters of carbon-thermal reduction were determined. The joint carbon-thermal reduction of zinc and iron oxides in granules from a mixture of blast-furnace sludge and steelmaking dust has been studied. The optimal parameters of the process were determined in terms of the content of solid carbon in the granules, oxygen in the gas phase, as well as the temperature range of reduction and the duration of the process. In order to simulate the conditions for the reduction of carbon-containing granules in industrial conditions, bench tests were carried out, which made it possible to determine the main operating parameters of the technological process for the processing of zinc-containing dusts of metallurgical production and justify the choice of the unit for these purposes. It is shown that the reductive roasting of granules from zinc-containing dust makes it possible to almost completely remove zinc from granules and metallize iron. A technology has been developed that makes it possible to obtain granules from zinc-containing dusts and process them in a rotary kiln with complete stripping of zinc and trapping it in bag filters, and using the metallic iron remaining in the granules in the metallurgical process.
