Iron Ore Sinter

The FINEX process is currently being operated at a scale of 1.5 Mt/yr hot metal [38]. The FINEX process is very similar to the COREX process; the major difference is that the FINEX process enables the direct use of sinter feed fine ore [37]. The scale of typical smelting reduction steelmaking plants is smaller than that of typical BF-based plants.

Sintering: Most Efficient Technologies for Greenhouse …

In a sinter plant, major areas of noise pollution are process waste gas exhauster fan, sinter cooler fan, and sinter crusher. Sinter plants act as sinks for solid wastes generated in steel plants. Wastes such as flue dust, LD slag mill scale, iron-bearing dust/sludge, etc. comprise of around 5% of total material used for sinter making.
