One of these processes is the hydrogen plasma smelting reduction (HPSR), which has proven to be a promising solution for iron ore reduction where water vapor is formed instead of CO2. However, due to the highly dynamic and sometimes unpredictable behavior of plasmas and their nonlinear interaction with the liquid oxides, the monitoring and control of the underlying processes must be improved. This article explores the usage of optical emission spectroscopy (OES) and image analysis for HPSR process monitoring at laboratory and pilot scale. The results cover the time evolution of the OES and camera data with the focus on the most interesting radiating species, such as atomic hydrogen, iron, and oxygen together with the FeO molecule.
