At the same time, the customers' requirements for product purity and consistent quality increase. Over the last few decades, processing and beneficiation techniques for iron ore have become more important in order to achieve a maximized utilization of ore resources and to produce competitive products according to …
A process adapted to upgrade ore is called beneficiation. Iron ore is upgraded to higher iron content through concentration. Iron ore is beneficiated to all around the world to meet the quality requirement of large steel industries. The company has been steadily participating in the development of Odisha and its people, he added.
Thermal beneficiation refers to the processes where iron ores are pretreated at high temperatures to achieve desired liberation in subsequent separation. During these processes, the weakly magnetic iron ores are typically converted into ferromagnetic magnetite by magnetizing roasting or metallic iron by deep reduction, which can be …
Hence, beneficiation option has to be used judiciously. Towards this, the enabler available is characterization and assessment of geological resource to explore the options of segregation, scheduling, sequencing and blending.
