 — Sinter is a product of the iron ore sintering process, which is a widely used pretreatment for ironmaking raw materials (Zhou et al., 2017a). More than 70% of the pig iron smelted in blast furnaces in China comes from sinter (Zhou et al., 2018a).

 — The objective of iron ore agglomeration is to generate a suitable product of granules in terms of thermal, mechanical, physical, and chemical properties. Sintering and pelletization processes are largely influenced by the source of iron ore and the way in which the beneficiation flowsheet is adopted.

 — In case of chromite, the temperature required for sintering is about 200 0 C more than that required for iron ore sintering. The process conditions for manganese ore sintering are almost similar to that for iron ore. The author has actively contributed to projects for setting up of batch type (capacity 15000 tpa) sinter plants at industry site.

Nitrogen oxides in iron ore sintering2.1. Emission characteristics. It has been determined that it is almost impossible to replicate technologies of low NOx combustion from other industries for iron ore sintering. Sintering is distinct from a coal-fired furnace, as it involves the three-way coexistence of gas, solids, and liquids.

line with the steel demands in India. Iron ore mining in Goa is completely in the private sector. Iron ore reserves in Goa are variously estimated to be around 1000 million tonnes. The Iron ore deposits in Goa are fines oriented. ... and more sinter in place of lumps. It has also opened up opportunities to use new technologies, innovations &

 — The raw materials for iron ore sintering used in this study came from an iron ore sintering plant in China. It mainly consists of iron ores, dolomite, limestone, quicklime, coke breeze, blast furnace return fines and sintering return fine. The main characteristics of the sintering raw material were shown in Table 4. It can be found that calcium ...

 — Sinter Plants, that produce iron ore sinter, are important units in an integrated steel plant. They face several operational challenges due to frequent changes in input raw materials, the inability to instrument key equipment in the plant, and the absence of real-time sinter quality measurement. To address these challenges, Virtual Sinter®, a …

 — Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents and solid fuel (coke).
