The present review handles the main characteristics of iron oxide reduction and its industrial applications. The reduction of iron oxide is the basis of all ironmaking processes, whether in a blast furnace or by direct reduction and/or direct smelting processes. The reduction characteristics of iron ores control the efficiency of any ironmaking process and the quality of the produced iron as well. Many controlling parameters should be considered when discussing the reducibility of iron ores such as equilibrium phase diagrams, reduction temperature, pressure, gas composition, and the nature of both iron ores and reducing agent. The different factors affecting the main routes of ironmaking will be highlighted in the present review to give a clear picture for each technology. Moreover, further innovations regarding the reduction of iron oxides such as reduction by green hydrogen will be discussed.

W pracy przedstawiono trendy badawcze z obszaru metali nieżelaznych na podstawie analizy publikacji zamieszczonych w ostatnim 10-leciu w czasopiśmie Rudy i Metale Nieżelazne, Recykling. Stwierdzono, że dominująca ilość publikacji (75 %) dotyczyła przetwórstwa metali nieżelaznych i inżynierii materiałowej. Około 19 % to publikacje z zakresu metalurgii ekstrakcyjnej, natomiast tylko 6 % publikacji dotyczyło geologii złóż, surowców mineralnych oraz przeróbki rud.

In the work a research tendency was presented within the range of non-ferrous metals on the base of publications in the last decade in the Journal “Rudy i Metale Nieżelazne Recykling”. It was stated, that the dominant number of publications (75 %) concerned processing of metals and materials engineering. About 19 % represented extractive metallurgy, whereas only 6 % of articles concerned geology, row materials and the ore processing
