The production process followed at Rashmi Metaliks makes the Sponge Iron unique and superior than its competitors Iron ore (Red Hematite) is extracted from the mines and taken to the Direct Reduced Iron (DRI) Plant where it is charged with different sizes of Coal (Carbon) by conveyor from different stock houses into the Rotary Kiln
iron ore beneficiation plant design and process flow iron ore beneficiation plant design and process flow Posted on 2012-12-30 by lmsh_hy Iron ore beneficiation is a complex process it aims to remove the unwanted impurity materials or gangues improve the iron ore grade and refine the concentrate for final applications
Major problem faced with the Indian iron ore is that though they are very rich in iron content they also have a high content of gangue material like silica and aluminium which obstruct the iron and steel production as the performance of the blast furnace lowers Iron ore sample found is a part of banded iron ore formation
Process Flowsheets Hard rock hematite deposits often require a combination of milling screening and on occasion fine classification to prepare a finely sized (-1 0mm) liberated feed for beneficiation by gravity separation This is typically followed by re-grinding of the tailings to liberate more hematite for further iron unit recovery by magnetic separation
