The reduction of chromium (IV) in industrial pellets and ore lumps was investigated by the thermogravimetric analysis (TGA). The main goal of the study was to examine in different temperature zones the behaviour of a sample consisting of industrial pellets mixed with lumpy ore and coke. The experiments were done under the carbon monoxide atmosphere in an electrical arc furnace. The sample composition (ratio between industrial pellets coke and ore lumps) was kept similar to the material used by industry to check the validity of the laboratory (one-element sample) experiments. The experimental work was performed in an electrical vertical arc furnace at the research laboratory in Delft University of Technology. During the research the kinetics of the chromite reduction in the temperature range of 1420-1520 °C were discussed. Samples were also studied using visual observations. The chromite ore tested during the experiments came from the mine in Finland.
