摘要

The properties of iron ores used in Japan have been drastically changed in the past 15 years. This was mainly caused by the increasing use of Australian ores containing a large amount of goethite, i.e., compound of iron oxide and water. Typically, the proportion of pisolitic ores, which are coarse goethite ores, has remarkably increased by about 3 times. Further, the large deposits of fine goethite ores called "Marra Mamba" have been exploited in Australia and started to export. Such trends are forecasted to continue in future. Since the change of the properties of used ores affects not only to the productivity and yield of sinter but also its metallurgical properties in the blast furnace, further improvement in the sintering technology/process is urgently required including the preliminary treatment process of raw materials.
