India is the fourth largest producer of iron ore in the world. Besides meeting its home demand a substantial portion of the iron ore production is exported. Iron ore export is an important foreign exchange earner for the country. In 1990-91 out of the total production of 55.59 million tons of iron ore 32.5 million tons (58.5%) was exported.

Iron ore sinter typically constitutes more than 60% of the blast furnace ferrous burden in modern blast furnaces in East Asia. Granulation and thermal densification are two important steps in iron ore sintering and determine the quality of the resultant sinter and the performance of the sintering process.

Iron ore sinter – A bulk material for blast-furnace smelting, which is made by sintering ore, limestone, fine coke, screened sinter and blast-furnace dust on special belt sintering machines. Sinter quality is determined by the Fe content of iron ore, strength, destruction during heating and reduction in a …

Sintering is an agglomeration process that is used in the iron industry to prepare ne grained iron bearing materials for use in the blast furnace. Sinter com-position usually depends on chemical composition of input materials, carbon content, oxidation potential of the gaseous phase, and temperatures in the sintering bed [1].
