 — Similarly, the influence of the three variables, namely, Al 2 O 3 in iron ore fines, total Fe in iron ore fines and total Fe in sinter were found to have favorable influence on sinter productivity instead of unfavorable influence found in the statistical correlation. All other 11 input variables had similar (favorable or unfavorable) influence ...

High grade iron ore less than 10% of the total reserves. 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.
