ROM iron ore with Fe less than 58 60% discarded as waste. After beneficiation iron ore availability can improve by about 50%. Steel community and the country demand technological solutions for utilising low grade ores. The technology task that would be imperative: 1. Utilisation of low grade iron ores after beneficiation. 2.

Sintering: A Step Between Mining Iron Ore and Steelmaking

World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.

Beneficiation Plants and Pelletizing Plants for Utilizing

In a beneficiation process, ore is finely ground to separate impurities. Therefore, the product ore inevitably becomes finer. Fines generated during the screening of high-grade ore can be agglomerated in a sintering plant; however, the finer fines resulting from the beneficiation process cannot usually be processed in a sintering plant and must be
