Sintering is the most extensively used and economic agglomeration process to prepare iron ore fines for blast furnace use. Granulation is the most critical factor controlling iron ore sintering process, as it improves sinter mix permeability. Currently, sinter plants are receiving significant proportion (up to 40%) of − 150 μm micro-fines in iron ore fines, which makes sintering difficult ...


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.


of agglomeration of iron ore fines for blast furnace feed. Research and development for the sintering process on the laboratory or pilot scale is typically conducted by means of a sinter pot test.

processes whereby iron is extracted from iron ores in the blast furnace and converted to steel in the basic oxygen steelmaking (BOS) furnace. Iron ore is prepared as a feed suitable for the blast furnace using the sintering process, an agglomeration process, in which blends of iron ore fines,


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.
