The processing of iron ore into raw materials that are ready to be processed into the material between the general uses of iron ore with iron content is high enough. In many countries of processed raw material is of primary iron India and China, raw materials used are low grade iron ore.
However, lowgrade hematite ores cannot be used directly in blast furnaces because of their low iron minerals content, which are associated with quartz and other gangue minerals (Yu et al., 2017). Therefore, lowgrade hematite ores must be treated by mineral processing methods (, flotation and magnetic separation) to obtain the iron ...
