摘要

voestalpine has set the objective of achieving low-carbon steel production with net-zero CO2 emissions by 2050. For this reason, a transformation of the steelmaking process is underway, including the replacement of carbon-based reducing agents by hydrogen and the increased use of electrical energy to overcome the melting enthalpy.

As partner of the project “Domestic ore for green steel”, the Chair of Mineral Processing is collaborating with the Chair of Ferrous Metallurgy, the Chair of Geology and Economic Geology, K1-MET GmbH, VA Erzberg GmbH, Primetals Technology Austria GmbH, voestalpine Stahl GmbH, and voestalpine Stahl Donawitz GmbH. The aim of the research is to support the implementation of low-carbon steel production using domestic iron ore.

The focus of the Chair of Mineral Processing is on preparing the iron ore concentrate for reduction—through comminution, classification, and calcination—as well as on processing the direct reduced iron to increase its iron content.
