Однако вторичное использование цинксодержащей ПГУ в черной металлургии приводит к накоплению цинка в футеровках доменных печей и частым неисправностям. Установлено, что оксид цинка находится в основном в связанном состоянии в составе фазы франклинита (Zn,Mn,Fe)(Fe,Mn)2O4. Исследованы процессы твердофазного восстановления пыли газоочистных установок электросталеплавильных печей с получением цинкового концентрата и губчатого железа, которые являются востребованным сырьем для цветной и черной металлургии. Определены оптимальные условия процесса восстановления, исследованы физико-химические характеристики, гранулометрический и фазовый состав исходных материалов и продуктов восстановления. Установлено, что применение комбинации восстановителей различной природы (угольный кокс и Н2) в процессе термообработки при 1100 °С и охлаждения в восстановительной среде (Ar/H2) позволяет получить губчатое железо с высокой степенью металлизации - 97,5 %.</p></abstract><trans-abstract xml:lang="en"><p>Currently, the volumes of use of dust from gas-cleaning devices (DGD) of electric steel furnaces are extremely insignificant, as they have an impact on the environment during storage, but at the same time, they represent the material that has a valuable composition (oxides of iron, non-ferrous metals, etc.) and is promising for recycling. However, the secondary use of zinc-containing DGD in ferrous metallurgy leads to the accumulation of zinc in the lining of blast furnaces and frequent malfunctions. It has been established that zinc oxide remains mainly in the bound state in the franklinite phase (Zn,Mn,Fe)(Fe,Mn)2O4. The processes of solid-phase reduction of dust from gas-cleaning devices of electric steel furnaces with the production of zinc concentrate and sponge iron, that are raw materials in demand for non-ferrous and ferrous metallurgy, are studied. The optimal conditions for the reduction process were determined, the physicochemical characteristics, granulometric and phase composition of the starting materials and reduction products were studied. It has been established, that the use of a combination of reducing agents of different nature (coal coke and H2) during heat treatment at 1100 °C and cooling in a reducing medium (Ar/H2) makes it possible to obtain sponge iron with a high degree of metallization - 97,5 %.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пыль газоочисток электросталеплавильных производств</kwd><kwd>оксид железа</kwd><kwd>оксид цинка</kwd><kwd>микроструктура</kwd><kwd>гранулометрический и фазовый составы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gas cleaning dust of electric steelmaking plants</kwd><kwd>iron oxide</kwd><kwd>zinc oxide</kwd><kwd>microstructure</kwd><kwd>granulometric composition</kwd><kwd>phase composition</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы выражают благодарность сотрудникам Института общей и неорганической химии НАН Беларуси Л.В.
