SINTERING AND PELLETISATION OF INDIAN IRON ORES

8 mm. HPS feed consists of iron ore as pellet feed fines, return fines and iron and steel work remnants, filter dust, additives and binders like limestone, dolomite, bentonite and coal dust. These micro pellets are fed onto a sinter machine to produce sinter cake, which is then broken down and smelted in a

Green Iron Ore Pellets For Sintering

Green Iron Ore Pellets For Sintering. difference between pelletising and sintering iron ore. Pelletizing , the free encyclopedia. Iron ore pellets are spheres of typically 818 mm 0.310.71 in to be used as The raw material is rolled into a ball, then fired in a kiln to sinter the particles into ore pellets as packed spheres in the blast furnace allows air to flow between the mixture in

Understanding the high-grade iron ore market

Only a few producers can supply iron ore pellets (and rarely lump) grades upward of 66-67% Fe suitable for the DR route. Iron ores that can meet the grade requirements are known as ‘DR-grade’, and the premium they command over benchmark indices is best reflected in the ‘DR-grade pellet premium’. This is important to bear in mind when looking to understand the dynamics of the high-grade
