The reduction of iron ore fines by means of the fluidized bed technology has become an alternative route in the field of ironmaking. To investigate the reduction behavior of these ores and to improve fluidized bed processes, a lab scale fluidized bed facility has been installed. With this equipment, the process behavior of iron ores can be determined close to industrial applications. Up to 5 kg of fine ores can be charged and fluidized with a wide variety of gas mixtures, containing H2, H2O, CO, CO2, CH4 and N2. Additionally a subsampling system was installed which enables the sampling of material. The scientific comparison of raw ore, subsamples and final material leads to a new way of fine ore characterization. Based on industrial processes also standardized tests were developed. With these procedures, globally traded iron ore brands can be tested close to industrial conditions.
