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.
The most common agglomeration process is the sintering of fine ore. As a rule, larger amounts of circulation material are used in the sintering plant. This often leads to increased emissions. A good solution here is a cloth filter system with a semi-dry sorption process. Küttner works here with Lühr in a very close cooperation.
